What we know so far and what features we want to see

Android 14 was publicly launched with the Pixel 8 series back in October 2023. We’re a few months into the new year, and Google has begun testing the next version of Android, now up to the Android 15 beta 1.2. This is still only intended for early adopters, but things are coming along.

In this article, we’re going to tell you everything we know (and think we know) about Android 15 so far!

Android 15: Name and release date

Google used to name Android versions with dessert codenames, but it strayed away from that tradition with the release of Android 10, where it decided to stick with only the version number for all future releases. So Android 15 is simply known as Android 15. However, Google still uses the dessert codenames internally. Android 15’s internal codename is Vanilla Ice Cream.

Google has begun testing Android 15 through two developer previews and one beta, though the final stable release is still several months away. Android 15’s release schedule includes beta releases going through July. That’s around when Android 15 will reach platform stability, meaning that no new features or APIs will be added so app developers can begin testing their apps against these public APIs. The next few releases will be focused on ironing out bugs and adding in a few new features here and there.

Google hasn’t mentioned when the stable Android 15 builds will be released, but we presume it will happen alongside the Pixel 9 series launch, possibly in October 2024.

If you use a recent Google Pixel device, you will be the first in line to receive the Android 15 update. OEMs will take a little longer to release their functional Android UX skins on top of the Android 15 platform. We are likely to see OEM-specific developer preview builds surface in the coming months for select phones. For those who don’t mind taking matters into their own hands, you can follow our guide and install Android 15 on your phone by yourself.

Once Android 15 is released publicly, OEMs will run their own beta programs for their skins, followed by stable releases. You can check if your phone has received the update through our Android 15 update tracker.

Android 15: New UI changes, features, and UX improvements

Android 15 looks quite similar to previous Android versions, but there are some notable changes that Google has introduced with this update. There are also functionality updates to several important features. All of these features have either been officially announced or have been spotted in the released Android 15 build.

With Android 15, users can share or record just an app window rather than the entire device screen. This feature was enabled first in Android 14 QPR 2 on Pixel devices but will now be available across the wider Android platform.

Satellite connectivity support

Android 15 extends platform support for satellite connectivity. The platform now has UI elements that are needed to “ensure a consistent user experience across the satellite connectivity landscape.” As part of these changes, apps can use APIs that allow them to detect when a device is connected to a satellite, which can give the app more awareness of why full network services are unavailable.

Android 15 also provides support for SMS apps and preloaded RCS apps to use satellite connectivity for sending and receiving messages. This means that satellite connectivity will not be limited to emergency uses only. Leaks had indicated that a deeper T-Mobile tie-in would be in place for satellite connectivity features, but Google has not yet revealed such details.

There’s a new function that can be found within the Notifications section. This function is called “Notification cooldown,” and it lowers the volume of successive notifications that come from the same app. It’s designed to prevent users from being overwhelmed by too many notifications.

While we spotted this feature in the first Android 15 developer preview, the first beta landed without it. It’s possible Google wants to leet this feature cook a bit longer before releasing it to the public.

Android 15 is adding new extensions for more control over the camera hardware on supported devices. New features added through these extensions include low light enhancements that give developers control to boost the brightness of the camera preview and advanced flash strength adjustments that enable precise control of flash intensity when capturing photos.

Android 15 Developer Preview 1 added a new “keyboard vibration” toggle that lets you universally disable keyboard vibration. When turned off, the system setting will override the setting within individual keyboard apps. When turned on, you can control the setting within individual keyboard apps, too.

Some forms of two-factor authentication (2FA) are safer than others, but many platforms rely on the most basic form of 2FA that sends one-time passwords (OTP) via text or email. However, Android 15 will fix that by adding a sensitive notifications feature that prevents your OTPs from being read by malicious Android apps.

Android lets you toggle Bluetooth through the Quick Settings tile, but most people leave the connection on to quickly connect to their accessories throughout the day. If you have multiple accessories around, you may find better utility with a Quick Setting tile that lets you toggle the individual connections to connect and disconnect to individual devices.

Android 15 brings this functionality, letting you click on the Bluetooth Quick Settings tile to open up a popup dialog that lets you perform more functions, such as toggling Bluetooth, connecting and disconnecting to individual devices, entering their settings page, and pairing new devices.

Android 13 lets users share or connect to nearby LE Audio streams, but Android 15 could make the Auracast feature easier to discover. This would allow Auracast-supported devices to broadcast audio to nearby Auracast devices using BLE without the hassle of pairing. There is a new “audio sharing” page that appears at Settings > Connected devices > Connection preferences to facilitate this audio sharing, as spotted in Android 15 Developer Preview 2.

High-Quality Webcam mode

Third-party webcam apps make it easy to use your Android phone as a webcam for your PC. Android 14 QPR 1 release for Pixel smartphones integrated the feature into the system, meaning you didn’t need a third-party app anymore. However, the output quality was pretty mediocre.

Android 15 Developer Preview 2 integrates a new High-Quality Webcam mode when you start the USB webcam feature on a Pixel device.

There is a new “HQ” symbol in the webcam preview, tapping on which disables any power optimizations that Google made that previously resulted in lowered quality. This mode significantly improves video quality, but the drawback is increased battery drain and heat buildup.

With Android 15, you can control whether you want to continue to use apps on the front display on foldables. Mishaal Rahman notes that this feature was present on Android 14 QPR betas but was removed and is now returning. You can either have the front display turn on whenever you fold your device; have it turn on for games, videos, and other apps, or never turn it on and lock the front display when you fold your device.

If these settings feel restrictive to you, Mishaal Rahman notes that Google is also testing a “swipe up to continue” option that replaces the “only games, videos, and more” option. This mode will let you continue apps on the cover screen by swiping up on the lock screen after you fold your device.

Better cover screen support

With Android 15, app developers can declare a property to allow their app to be presented on the small cover screens of supported flippable devices. These cover screens are often too small to run full-fledged apps with a good user experience, but app developers can opt-in to support these cover displays.

Persistent taskbar for large-screen devices

Google added a taskbar dock for large-screen devices with Android 12L. It took the entire width of the screen and stayed there persisently, but this meant it took up a lot of screen space rather permanently. With Android 13, the taskbar shrunk in size to a smaller pill-shaped box, but it also became transient, appearing for a few seconds only when the user swiped up on the gesture bar. While the change was good, it also made accessing the taskbar dock a two-step process, which may not work for heavy multi-taskers.

With Android 15 Developer Preview 2, Google is giving users the option to choose the transient taskbar or to make it permanent with a new “always show taskbar” toggle.

This way, users can have the best of both worlds, suiting their needs.

Health Connect

Android 15 includes updates to the Health Connect by Android platform, which adds support for new data types across fitness, nutrition, and more.

Virtual MIDI 2.0 Devices

Android 13 added support for connecting to MIDI 2.0 devices via USB, which communicate using Universal MIDI Packets (UMP). Android 15 extends UMP support to virtual MIDI apps. This enables composition apps to control synthesizer apps as a virtual MIDI 2.0 device, just like they would with a USB MIDI 2.0 device.

HDR headroom control

In situations where you have some HDR content on your screen but more SDR content (for example, an HDR thumbnail while the rest of the content is in SDR), the HDR content can overpower the perceived brightness of the rest of the SDR content. Android 15 allows apps to control the HDR headroom, so they can avoid such situations.

Loudness control

Edge-to-edge apps by default

Android allows apps to use the entire height and width of the display to showcase their content, but many apps do not take advantage of this. Android 15 forces apps to go edge-to-edge by default.

Smaller changes

There are a few smaller changes as well that have been either announced by Google officially or spotted on Android 15 builds so far:

• There is haptic feedback when adjusting the display brightness through the Quick Settings slider (h/t Mishaal Rahman).
• New APIs allow smoother NFC experiences by allowing devices to listen but not respond to NFC readers. In some cases, this would allow for a one-tap transaction.
• Android has a new PDFRenderer API, allowing apps that use it to render password-protected PDF files, annotations, allow for form editing, searching, and selection with copy.
• The Pixel Launcher has a new “apps list settings” page that contains the “swipe to start search” settings toggle (h/t Mishaal Rahman).
  • In the future, this page could also house a new “show long app names” setting that would let you display long app names on two lines in the search results and apps list.
• New accessibility settings for use with physical keyboards: You can enable Sticky keys, Slow keys, and Bounce keys when you are using a physical keyboard on a device with Android 15. This feature will be useful for users with motor disabilities and those who face difficulties typing on a physical keyboard.
  • Sticky keys make it easier to enter keyboard shortcuts in quick succession.
  • Slow keys hold down the duration that the user has to press before the system accepts a keypress.
  • Bounce keys help ignore rapid, repeated presses of the same key.
• Android 15 also shows a preview of the keyboard layout that you select in physical keyboard settings, in case your physical keyboard has a different physical layout.
• Android TalkBack is gaining support for Braille displays, which use human interface devices over USB and Bluetooth to improve accessibility.
• You can now set a wallet app as a default, allowing you to set something other than Google Wallet as your default wallet service.

Android 15 continues work in the Android Dynamic Performance Framework (ADPF). ADPF is a set of APIs that allow games and performance-intensive apps to interact more directly with the power and thermal systems of Android devices. With these APIs, you can monitor system behavior better and then go a step further to optimize performance to a sustainable level that doesn’t overheat devices.

ADPF consists of these main features:

• Thermal-state monitoring
• CPU performance hints
• Fixed-performance mode

On supported devices, Android 15 will add new ADPF capabilities, namely:

• A power efficiency mode for hint sessions to indicate that their associated threads should prefer power saving over performance. This is said to be good for long-running background workloads.
• Hint sessions can now report CPU and GPU work durations, allowing the system to adjust CPU and GPU frequencies together to best meet workload demands.
• New thermal headroom thresholds to interpret possible thermal throttling status based on headroom prediction.

App and game developers can use these APIs to make their apps and games work better on devices that would support these APIs.

iOS has a handy feature that lets you “offload apps” to reclaim some storage space. You can uninstall apps you use rarely but keep the user data around. So when you reinstall the app, you can get back where you left off.

With Android 15 Developer Preview 2, Google baked in a similar app archiving feature. It then formally announced the feature with the launch of the first Android 15 beta, all but assuring us that this feature will launch.

When an app is archived on Android, most of its working files will be removed, while a stripped-down version of the app will be retained. There will be a home screen icon which, when clicked, will trigger the Google Play Store to unarchive the app.

Google already lets you opt into auto-archiving through the Google Play Store. Since the feature is run through the Play Store, you cannot archive or unarchive apps through your phone’s Settings app.

Android 15 changes this behavior by adding a new Archive and Restore button on the App Info page.

This way, even apps installed from outside of the Play Store could be archived from an easily accessible location.

In this demo, an app that is 387MB in size has been archived to just 18MB in size, a staggering 95% decrease. After the archive, the app was restored to show that none of the user data was lost in the process.

Android 15 will not only let you manually archive apps but also let you choose whether to have the OS automatically archive apps that you do not use often. Further, other app stores beyond the Google Play Store will also be able to get the feature working if they support the necessary app formats.

Locking WebView into memory

Android 15 Developer Preview 1 is locking into memory the trichrome library that Android System WebView uses. Many apps use Android System WebView to display internet content, as it helps them avoid building a web browser from scratch for such a task. Since the process is locked into memory, the Android system will deprioritize killing the process during regular RAM management operations.

In theory, apps that rely on WebView could see a marginal improvement in their performance to the extent of their use of WebView, especially on devices with less RAM where processes are more frequently purged from RAM.

Smaller changes

• Android 15 has new APIs that allow apps to track their app startup and stop state, display their detailed app size information, and more.
• There is a new “disable default frame rate for games” setting in Developer Options that disables limiting the maximum frame rate for games at 60Hz.
• Apps optimized for Android 15 will now be edge-to-edge by default. This means that developers won’t have to call on additional classes to show their content beyond system bars.

Privacy Sandbox on Android

One of the highlights of the Android 15 update is that it incorporates the latest version of the Privacy Sandbox on Android.

Privacy Sandbox on Android is a multi-year initiative from Google that introduces more private advertising solutions that limit the sharing of user data with third parties and operate without cross-app identifiers. The goal here is to develop an effective and privacy-enhancing advertising solution where user information is protected. This is needed to cultivate a healthy app ecosystem, which is needed for the overall health of the Android platform.

File integrity

Android 15 introduces a new FileIntegrityManager API that uses a feature called “fs-verity” in the Linux kernel. With fs-verity, files can be protected by custom cryptographic signatures, ensuring that they do not get tampered with or corrupted. So app developers can rest easy knowing that their app functionality and data are not compromised in any way.

Screen record detection

Android 15 will allow apps to detect when they are being screen-recorded. For apps that perform sensitive operations, developers can invoke APIs to allow the content to be hidden within such screen recordings.

End-to-end encryption of contact keys

The first beta introduced an OS-level API that provides end-to-end encryption for contact keys. This feature allows the user to manage and verify other people’s contact information securely.

Smaller changes

• On Android 15, you now have to authenticate your identity using the fingerprint sensor or other lock screen security options if you want to change the USB mode on your phone when it is connected to a computer.
• If you head to Settings > Security & privacy > More security & privacy, you can toggle on two nw security features: “security notifications” and “require encryption.” These will help protect you against “stingray” hacks. You can find out more about this in our deep dive into Android 15’s anti-stingray protections.
• WEP is an older security protocol for Wi-Fi that is not as secure as modern methods. Android 15 will put a toggle at Settings > Network & Internet > Internet > Network preferences that will allow you to disable connections to networks that use WEP.

Android 15: Leaked and upcoming features

In addition to all the features that Google has officially announced, and those that have been spotted in the Android 15 Developer Preview 1 build, there are plenty of changes that have been leaked and are rumored to arrive on Android 15.

Satellite Messaging with T-Mobile

Google has confirmed that satellite messaging support is coming to Android 15. However, we don’t know much about how this will actually work. Based on what we know so far, T-Mobile (in conjunction with partner Starlink) might offer a paid subscription that would allow you to send satellite messages natively in the Messages app. These messages would work anywhere as long as you have a view of the open sky. Even if there are zero cell towers around, you could still text with your friends (for a price).

This is what the Satellite Messaging page within Android 15 could look like:

If this ends up happening, it would be a significant blow against the iPhone. While recent iPhones have access to free satellite messaging, they only can be used in emergencies to contact help. Android users being able to use them for whatever they want would be a major win.

Revamped status bar with new icons and haptics

Google could refresh Android’s status bar icons with a new look and add haptic feedback to the Quick Settings and volume panels. The changes are not live yet, but we expect them to go live in Android 15 Beta 2, possibly.

With Android 15, some of the status bar icons may feature a segmented design. The battery icon may also finally support showing the current battery level inside the icon rather than to the right of it.

The charging chip which appears when you plug in your device is also being updated.

Users will be able to disable the battery level if they don’t like it. Here is what it will look like without the battery level.

Android 15 may also add haptic feedback to the Quick Settings panel, such as when users long-press on tiles such as the Bluetooth tile. There will also be some haptic feedback when moving the volume slider to adjust the volume stream.

Lock screen widgets for tablets

Android supported lock screen widgets with Android 4.2 Jelly Bean, but the feature was killed off in Android 5.0 Lollipop. Since iOS brought lock screen widgets with iOS 16, Android will bring widgets back to the lock screen with Android 15.

However, recent evidence suggests this will only apply to tablets, and possibly only the Pixel Tablet. We need more information to be certain, but that’s the way things are looking right now.

Android 14 laid the groundwork for the OS to track battery health information, while Android 15 could make battery health information accessible to users. The OS could show the estimated percentage of charge your phone’s battery can currently hold compared to when it was new. This would give users a clearer idea of how far their battery has degraded.

There are many variables involved in this feature’s coming to light, though we cross our fingers and remain optimistic. iPhones already report their battery health in an easy-to-read manner, and that information has been valuable to users in deciding the condition of pre-owned units and whether they should get their batteries replaced.

Storage chip health

In addition to battery health information, Android 15 is also preparing a new feature that will tell users the remaining lifetime of their device’s internal storage. Under the hood, the Device Diagnostics app will utilize a new storage lifetime API in Android 15 that “returns the remaining lifetime of the internal storage device, as an integer percentage.”

However, only some devices are expected to report the remaining storage lifetime with 1% granularity, and most will report it at a less accurate 10% granularity, if at all they support the feature (as Google doesn’t require devices to support it).

Android 15’s latest builds feature a new volume panel design. It features much thicker, pill-shaped sliders. A dot is placed at the end where the slider’s maximum value is, and the icons are also tappable to quickly mute that stream.

Android 15’s new volume panel is also collapsible. Tapping the button next to the media volume slider collapses or expands the panel. Whenever there’s active media playback, the volume panel is collapsed by default. Otherwise, it opens in its fully expanded state.

In addition to the new design, the volume panel will also surface additional controls for spatial audio and “noise control.”

Android 15 will add the new Powered Off Finding API that would enable powered-off finding across compatible Android devices, as per a report. These APIs would be contained within the Project Mainline module called “Tethering,” which can only be used on devices that are running Android 15. Further, this API will be utilized by the upgraded Find My Device network, which will be rolled out through the Google Play Services.

What Powered Off Finding API does is that it allows a device to fire off precomputed Bluetooth beacons, even when the device is off (presuming there is some reserve power available for this action). With these Bluetooth beacons, nearby Android devices will be able to help track the switched-off device, similar to how iPhones can be tracked when they are powered off.

This feature would need hardware support to allow the Bluetooth controller to work when the rest of the device is powered off. The feature also requires the phone to support the Bluetooth Finder HAL so that Android can enable Powered Off Finding mode.

The feature is expected to debut with the Google Pixel 9, but it could also make its way to the Pixel 8 series as the devices include the necessary hardware.

Android allows any app to become the default assistant app on your device, but it doesn’t let them use wake words like “Hey Google” in the background. Your phone would have to constantly listen to audio through the microphone in order to pick up the designated wake word.

Previous versions of Android allowed wake word detection, but Google removed the feature with Android 12. This upcoming feature could bring back the functionality, letting apps like ChatGPT and Amazon Alexa become accessible with a wake word, even when your phone’s screen is off. Pre-Android 15, only Google Assistant and Bixby on Samsung phones allow for hands-free voice activation through a wake word.

Thanks to some digging, we have more information on Android 15’s Private Space, including a hands-on of Private Space. When the feature goes live, it will be available at Settings > Security & privacy > Private Space. Google will also recommend that users create a new Google account dedicated to Private Space, as a shared account could leak data outside of the private space.

Users will be able to automatically lock their private space, change the screen lock, automatically hide private space from appearing in the app list, make sensitive notifications appear on the lock screen when private space is unlocked, or delete the private space.

You will also be able to quickly install an app in your private space through the Pixel Launcher by tapping on a button in your primary profile.

Android allows you to run apps in split-screen mode, but you have to choose the apps every time you launch them. Android 15 could let you save split-screen app combinations as an App Pair, so you can quickly relaunch a pair of apps into split-screen mode.

When you save an app pair, an icon is added to the home screen that shows the two apps in a saved pair configuration. Clicking on this icon will launch this app pair configuration.

In freeform mode, the app will get a title bar that shows the app’s name and icon, a dropdown to open the menu to change the windowing mode, a maximize button, and a close button. The window can be freely moved around and resized. Resizing the window temporarily hides the app’s content to make it easier to see the window as it’s being resized. Windows can be dragged to the left or right edge to snap them to that half. Once an app is full-screened, you can drag instead of tap the handle at the top to quickly turn the window into a freeform or split-screen one.

This screensaver isn’t currently available, but we activated it to show off how it works. It simply shows the Google Home controls that you have favorited and the current time. The UI is even the same as the one that appears in Android 14 when you set the Google Home app as Android’s Device Controls provider and open the smart home controls dashboard via the aforementioned Quick Setting tile or lock screen shortcut.

New Pixel Launcher features

Google is preparing a bunch of changes specifically for the Pixel Launcher with the Android 15 update. These are the new features coming to the Pixel Launcher with Android 15:

• New animation when swiping up on an app to return to the home screen.
• Better widget recommendations across recommendation categories: Essentials, Social, Entertainment, Health and Fitness, News and magazines, Weather, Suggested for You, and Your Chill Zone.
• A “+ Add” button in the widget selector to make it easier to add widgets to home screen.
• A new pill in the Recents menu opens shortcuts for the app, namely the app info page, entering split screen mode, and pausing an app.

These changes have been spotted through feature flags. There is a chance that not all of them will make it to Android 15. It also remains to be seen how many of them get carried over to the AOSP Launcher as the Pixel Launcher is Pixel-specific.

Easy pre-set mode to improve readability and ease of navigation

Strings within past Android builds indicate that Google has been working on a feature called “easy pre-set mode,” which could arrive with Android 15’s later releases.

Easy pre-set mode could optimize the Android experience for improved readability and ease of navigation. It would do so by enlarging icons and text, adding contrast and boldness, and adding navigation buttons to the bottom of the screen. It would also set the current wallpaper to a black color, so you can have an easier time figuring out your icons and icon labels. A feature like this would be very handy for elderly or less tech-savvy users as it would make it easier to use the phone.

Android 15 has a new “color contrast” settings page that is hidden by default. When manually activated, this page lets the user adjust the contrast of text, buttons, and icons to make them stand out more in apps.

Headphone loud sound alerts

This feature was intended to arrive on Android 14 but arrived with Android 14 QPR 1 (h/t Mishaal Rahman) on Pixel devices. As such, the changes it introduces are expected to be available for the wider Android platform with the Android 15 release.

This new feature monitors sound doses over time to protect users from the damaging effects of excessive or prolonged sound exposure. It complies with regulatory requirements in the EU and is also different from the safe media volume limit feature (which focuses on a fixed volume). The new feature warns when the music is playing loudly (volume measured through the audio signal) for a while.

Adaptive timeout for screen timeout

We’ve spotted code within Android 15 that indicates that Google is also working on an adaptive timeout feature for the upcoming Android release. This feature will automatically turn off your phone’s screen early if you are not using your device. With adaptive timeout, you may be able to set an extended screen timeout and still enjoy the security and battery benefits of a shorter timeout when you are not using your phone.

It is not immediately clear how the feature will be implemented. There’s a chance that this feature doesn’t make it to AOSP but gets reserved for Pixel UI.

“Even dimmer” display brightness

Android 15 could include an “even dimmer” display brightness option. As the name suggests, this setting toggle would allow your phone’s display to go dimmer than usual. This feature could work alongside adaptive brightness, going even dimmer than usual when the ambient lighting is super low but automatically returning to normal brightness when the ambient lighting is high.

Bluetooth auto-on

Google is upgrading Android’s Find My Device network to leverage the wide network of Android devices. This upgrade will rely on Bluetooth beacons from participating devices, which will be used to locate other nearby devices. However, if participating devices have their Bluetooth switched off, the network will lose efficacy.

With Android 15, Google is building a “Bluetooth auto-on” toggle. When selected, this will pause the Bluetooth radio temporarily and switch it back on the next day instead of disabling it until the next time the user toggles it. Only system apps will be able to toggle your phone’s Bluetooth radio without your knowledge. There may be other restrictions in place that could prevent this feature from being available on all devices.

On iPhones, toggling Bluetooth or Wi-Fi from the Control Centre (aka the quick settings panel) merely disconnects accessories until the next day. It does not disable the radios, and both Bluetooth and Wi-Fi continue to remain available for Apple ecosystem features. To disable the radios, you need to toggle Bluetooth and Wi-Fi from the Settings app. So Google could have been partly inspired from here.

NFC wireless charging

Android 15 could introduce support for NFC wireless charging. NFC wireless charging works with significantly smaller antennas than Qi wireless charging. It is ideal for tiny smart devices like earbuds, styluses, smartwatches, and tracker tags, though the devices will need to feature an antenna that manages both communication and charging.

Hide unused notification channels by default

Notification channels are categories of notifications that an app can deliver. App developers can create channels for the various types of notifications that their app serves, and users can be selective about the channels they allow notifications from.

However, app developers can decide how many notification channels their app needs, and there are situations where they create too many channels. To combat this, Android 15 could hide unused notification channels by default. A three-dot menu button will house a new “show unused channels” option that you can use to showcase the unused channels.

You can see how much cleaner figuring out notification channels gets when you hide the unused notification channels.

Selectively hide sensitive content when screensharing

In addition to letting apps know about screenshots, screen recordings, and screenshares and allowing partial screen recordings, Android 15 could also prevent apps from leaking sensitive information. There is a new feature internally called “sensitive content protection.” With this, apps that display sensitive information only occasionally can selectively block those fields from appearing in screen shares and recordings rather than disabling screenshots, screen shares, and recordings entirely.

Enhanced Confirmation Mode

Enhanced Confirmation Mode in Android 15 builds upon Android 13’s Restricted Settings feature. Enhanced Confirmation Mode checks an allowlist that’s preloaded in the factory image, exempting packages and installers mentioned therein as “trusted packages.” Trusted packages can, in turn, install apps that are eligible to be exempt from any restrictions on being granted Android’s Accessibility or Notification Listener services (which Android 13 marked as Restricted Settings).

This feature essentially closes a loophole that Android 13’s Restricted Settings brought about.

New Project Mainline module: WebViewBootstrap

Project Mainline is referred to as the biggest change to Android since Project Treble. The purpose of Project Mainline is for Google to wrest control of framework components and system applications that are critical to security and maintaining development consistency away from OEMs, thereby reducing the overall fragmentation in the OS. Project Mainline was introduced with Android 10, and we’ve seen Google add new modules with every Android release.

With Android 15, we will get a new Project Mainline module called WebViewBootstrap. According to a report, this module will handle the core framework APIs that Android uses to integrate WebView into apps. Google already handles the distribution of the core browser component of WebView through the Play Store but pushes the core framework APIs to AOSP for OEMs to pick up from. Switching from AOSP to a Project Mainline module will give Google the ability to update the core framework APIs without OEM intervention.

This new module could launch with Android 15 but could possibly be optional for OEMs to include in their builds. It could be made mandatory to include with Android 16 instead.

New Location Privacy HAL

Android 15 could include a new radio HAL API that allows for location privacy settings. This API will give the user some more control over how their carrier can request a network-initiated location request for non-emergency use cases.

Proactive alerts when using an insecure connection

Android 15 will warn you when a cellular network collects your device’s IMSI or IMEI, as well as when the network attempts to change the ciphering algorithm to create an insecure connection. Your device does need to support newer hardware APIs for this feature to function. The cellular transparency feature will present a notification that informs the user that their device’s IMSI or IMEI has been accessed, and users will be able to access it at Settings > Security & Privacy > More security & privacy. The page will also likely include a toggle to “require encryption,” which will disable null-ciphered connections at the modem level on supported devices.

Android 15 could raise the target SDK version, making older Android Marshmallow apps incompatible

Google introduces new APIs and features with every Android release and banks on developers keeping their apps updated with these new APIs and best practices. However, older apps still exist, and developers may not be keen to keep them updated for various reasons. Regular users still need to be protected against the drawbacks of outdated APIs, so the Google Play Store hides older apps from users. Users could still sideload them, but Android 14 began blocking sideloading apps that were built for Android 6.0 Marshmallow, i.e. with a target SDK version 23.

With Android 15, Google could raise this target SDK version to 24. This means that apps targeting APIs for Android 6.0 Marshmallow will not be easy to install, and you’d need to default to apps built for Android 7.0 Nougat at least.

---

That’s everything we know (and think we know) about Android 15 so far! Be sure to bookmark this page, as it will be updated often with new leaks and announcements.
