Google has released the fourth and final beta version of Android 13
After six months of testing, Google developers released the fourth and final beta version of the Android 13 operating system.
Since this is the last test version of the software, the developers have focused on fixing bugs. In addition, Google has optimized performance and autonomy.
The latest Android 13 beta means that all subsequent OS updates will be stable. The company has not yet said when exactly Android 13 will be released, but it can be assumed that the firmware will be released in the middle or at the end of August. Of course, Google Pixel smartphones will be the first to receive the update.
