ShubhSach , via OnePlus 6T , Oct 17, 2021 : Sometimes when I try to unlock my phone face ID, it doesn't work and I get an error saying that camera is being used by another application, however, no application ks running in the background and even when I try to open the camera app or any other app where camera is needed, it doesn't show anything as well. In order to fix the same, I have to open and close the camera alp a few times. This issue was rare before, however, I've been getting this error quite often now a days. Has anyone else come accross similar issue? If yes, any suggestions how to fix the same or is it a software bug?
