Google’s latest Android version – Android 8.0 Oreo does not seem to get a breather from issues. Once again, a bug has brought the OS under the limelight for all the wrong reasons. This time around, a bug has plagued the “Adaptive Icons” feature on the OS, and it is setting the devices to go on endless boot loops. This has led many users to factory reset their devices.

The bug was found by Jcbsera, the developer behind the Swipe for Facebook Android app. It does not affect apps that do not use the adaptive icons feature. The adaptive icons feature introduced on Oreo allows icons to change size or shape according to the launcher used by the user or the device it is on. For example – adaptive icons will appear in shapes like square, rounded, or circle depending on the active theme or launcher on the device.
