Bhavi_j , via OnePlus 7T , Jan 25, 2020 : I've got a oneplus 7t ( 8gb + 128 gb ). i recently shifted from india to Canada and i factory reset my phone twice or thrice cause once i forgot the pin code and once i did it in order to check if i code change my country from india to Canada. After a while I've been facing a bug in the hidden tab. when i open hidden tab and i place my fingerprint then either it opens a previous used app or it shows a black blank screen and then no gesture works, so usually i click on the settings option in notification panel after getting into this situation as it opens settings app and i am able to use gestures to go back to home screen. This thing happens twice or thrice a day. Is there any solution or should i reset my phone again and one more thing, I am not getting any updates for the software as i did in india as oneplus is not releasing any updates for the phone.
