yadavash007 , via OnePlus 7T , Apr 20, 2021 : Hi, I bought OnePlus 7T in Feb 2020. All the sensors and other features were working fine for me. Yesterday I got a notification to update to Android 11 and I did update my phone. But now the screen light doesn't go off during call. Rest all sensors are working fine. Secondly, speed of my phone also reduced after update. Whenever I click any notification in the notification bar, there is a delay in opening the app, be it the message app or WhatsApp. Sometimes it feels that my touch on notification didn't work because of the delay opening of the app. Please resolve or help on both the issues.
