mohansundaram1997 , via OnePlus 7 Pro , Aug 12, 2020 : Hello one plus community, I have a one plus 7 pro.Ever since I received the update 10.3.3.GM21AA. Here's the list of problems happened in the chronological order: 1. when I change to front camera it doesn't work, the front camera pop-up works fine but camera doesn't show any image on display, I have only a black screen and I can't close the camera app or switch to rear camera (which was working fine then) either, I had to close it from the "recent apps" section. This happens across all the apps that uses front camera ( Instagram, Facebook, WhatsApp, etc ). 2. Since the front camera doesn't work now I disabled the facial recognition feature and i had been managing with my rear camea, After about a week time, the rear camera doesn't work same as front camera.. all I have is a black screen when I open the camera app or any other app that uses the Camera Api... And I can't turn on the flashlight from the settings. 3. Here's where the problems get even more weird, about the same time as my entire camera Api doesn't work.. when i launch the official YouTube app, it fails to fetch any info from youtube, like I have a connection issue.. but I have no connection issues when I use other apps, and youtube works on browsers. These are all the problems im currently experiencing right now, even after I have updated to the the current version of oxygenos ( 10.3.4.GM21AA ) the issues I specified still present. I have tried "factory reset" as well and it doesn't fix the problems for me.
