007me, Nov 6, 2018 : Hi, I've updated yesterday my OnePlus6 to the latest Oxygen 9.0.2 and this was a big mistake! It is full of bugs. 1. when I'm typing in WhatsApp the keyboard is dropping down and the window is freezing. Have to go to homepage open WhatsApp again and continue to type. 2. When on phone call the dialer app is moving to the background leaving the small "call" button on top. 3. Gestures works strange, it doesn't always return to the previous screen. And many more. Any fix on the way? Is there a way to rollback to the previous Oxygen version?
