It was my understandig that the phone automatically adjust resolution when needed. Maybe this app defaults to 1096x2560 ? Or the app is just incompatible to Android 11
The phone only is 4K when the app supports it , these apps don’t pick up the changes ... Netflix is 4K and so is you tube to name a few .... it’s normal no way would you have decent battery life if it ran at 4K all the time
Droid Info already showed the FHD+ resolution 1096x2560 on Android 10 for my US XQ-AT51. Device Info HW however shows the 4K resolution in the GENERAL tab, and the FHD+ in the SYSTEM tab.
