Android 15 Features and Changelog

Here are all the Android 15 features and changes. Most are for developers, despite being a public build. Apart from the one listed for the Beta, here is the complete changelog.

Private Space offers the ability to hide apps on your device

Private Space allows users to create a separate, secure area on their device to keep sensitive apps hidden from prying eyes, protected by an additional layer of authentication. This feature uses a distinct user profile. When the private space is locked, the profile is paused, and any apps within it become inactive. Users can opt to use the device lock or a separate lock for the private space.

Apps in the private space appear in a separate container in the launcher and are hidden from the recents view, notifications, settings, and other apps when locked. User-generated and downloaded content, such as media or files, along with accounts, are kept separate between the private space and the main space.

The system sharesheet and the photo picker can provide apps with access to content across spaces when the private space is unlocked.

Predictive Back Gesture

Android 15 brings the predictive back gesture feature enabled by default, enhancing navigation by showing where the back gesture will lead you. This feature, previously available only in developer settings, now integrates seamlessly into apps and system interfaces, including the Pixel Launcher and quick settings.

Private Space offers the ability to hide apps on your device

Partial screen recordings offer a significant improvement in managing screen capture on your phone. Typically, when you start a screen recording, it captures everything on your screen—your home screen, every app you switch to, and all activities. However, with the screen recording, it’s now possible to record individual apps selectively.

When you begin a screen recording, you can choose to record the entire screen or just a single app. For instance, if you select the single app option, you’ll be prompted to choose which app you want to record.

When you review the screen recording, it appears normal until you switch to another app. The recording will only show the selected app, ignoring other apps you might have accessed in between. This focused recording method ensures that only the content you want to share is visible. You won’t have to worry about capturing private messages or sensitive information inadvertently.

Redesigned Sound Panel and Spatial Audio

The Sound & Vibration menu under the volume slider has been revamped with wide fill bars and animated interactions. For Pixel Buds Pro users, new controls for spatial audio modes add to the customization options, allowing you to switch between modes with ease.

Wallpaper & Style App

The Wallpaper & Style app now features a “Color Contrast” setting. This makes it easier to adjust dynamic color contrasts, providing immediate visual feedback on how it affects your apps.

Bluetooth Auto-On Feature

A new switch in the Bluetooth settings allows you to automatically turn on Bluetooth the next day, making connectivity more convenient for connectivity.
