on k20 pro, i have this issue where the big title games like pubg hangs or screen freezes for few seconds. please fix it.
probably something to do with audioPolicyEngine or AudioFlinger idk.
there is a huge battery drain on raphael since i upgraded to 9.1. like 10-12% per hour on standby. I had 7.something version previously and didn't have this issue/was like 2-3% per hour. please fix it.
