A Google developer spilled the beans on the imminent first preview of Android 15. The first developer preview for Android V (Vanilla Ice Cream) as it is internally known will be released tomorrow, February 15. This timing makes sense and is a week later than last year’s first developer preview for Android 14.
Android 15 is expected to offer a Private Spaces feature which allows you to lock some apps from appearing in your app list. Lock Screen widgets are expected to make a return and Google is expected to bring full-screen apps that will display content under the navigation and status bars. Android 15 DP will be available for Google Pixel 6 and newer Pixel devices.
Developer preview builds are only recommended for app developers to use for app testing but as long as you have a supported Pixel device, you'll be able to download and install the firmware build.
