I upgrade my zenfone to Android Pie, and lots of bugs for this updates.
1. ZenUI interface sometimes lag , crash, or stop responding.
2. Sound/Audio System its like monotones, no bass on headset/Earphones and volume not accurates
3. Games , like Mobile legends always rotating even the auto rotation is off, fix the Sensors pls.
4. Battery Drain always the problem for all phone after the updates
5.Screen Auto/Manual Brighness Ration not Acuurates
