Google has returned Android 15 to the development phase for further testing, delaying its expected release to October. The decision was made to enhance the software's stability before public availability. Although beta testing wrapped up in August, Google is focusing on refining the software. The source code for Android 15 may be shared with developers as early as September 3, but the stable version is still some time away. The October timeline aligns with last year's launch of Android 14, but the situation feels unusual due to the lack of a concrete release date. The Pixel 9 series is anticipated to debut alongside the stable version of Android 15.
