Google has just launched the latest version of its mobile operating system Android, the Android 9 Pie. Right after the announcement, the company started rolling out the Android 9 Pie OTA updates for its Pixel devices and shortly after the company started uploading the source code of Android Pie to the Android Open Source Project (AOSP). Uploading the source code of the latest changes done to Android to AOSP is a regular checklist for Google and this also allows independent Android developers to download the source code and start compiling it for the devices of their choice.
AOSP enables these developers to make custom ROMs so that they can port the latest version of Android of their devices. AOSP is also a great place for developers to dig through the source code and look out for hidden features that Google has not openly talked about. Similar to previous source code releases on AOSP, developers have started combing through the code for Android 9 Pie to look for hidden features. According to a report by xda, the code has confirmed that Always on Display mode on Android now comes with support for wallpapers.

According to the report, this was first spotted back in Android P Developer Preview 1 for Google Pixel 2. Developers confirmed that Google is actively working on this feature and it may launch this new feature along with the upcoming Google Pixel 3 lineup. According to the code, the wallpaper will be hidden after 1 minute and the system transition from the wallpaper to the black background is set to 400 milliseconds.
The report pointed out that this is not the only new feature that the company has added in Android 9 Pie. Other additions include keeping RAM-intensive games in the memory if the user accidentally exits them, Android 9 Pie remembering the sound levels of all the Bluetooth devices, and mandatory rollback protection for Android Pie adopters.
