dalavaiGanesh , via OnePlus 7 Pro , Dec 4, 2021 : My frunt and back camera suddenly stopped working. When I came accross some feeds I thought it was due to software update from one plus. So I have reverted back the update to android 11. Still the problem persists, is there any way to revert back. My mob is out of warranty and can't spare to pay lot of amount for the repair. Thanks in advance.
