A71 after update Android 11 ONE UI 3.1

I bought A71 an year ago and its performance it perfect before the last update it slightly lags during game but is optimized after the one ui 3.1 update but i find some features was better before like in landscape mode the notification panel doesnt cover the whole screen it appears in the middle which is not so suggested other than that recovery mode cannot be enabled without connecting to a pc which are only features partially removed other than that the phone is perfect with the best possible performance
