X1603115683451 , via OnePlus 8T , Dec 1, 2020 : I am using OnePlus 8T since a month. Getting it regularly software update. Today I faced weared screen freeze issue. 1. I used my phone for a while and used some apps. 2. Locked it and after some time when I tried to unlock, phone did not responded to any input. 3. Tapped the screen for 3-4 times and it showed fingerprint sensor circle but that too was completely white and nothing was happening when I put finger to unlock. 4. Basically I was getting only a complete white circle at fingerprint sensor place and nothing else was happening. 5. Also nothing was useful on OnePlus community site, I searched for How to restart OnePlus when hang and found one thread on Quora. It worked and hence I sharing details here. Steps to restart when hang: 1. Press and hold power button. 2. Keeping the power button pressed, Press and hold both up and down volume button at same time. 3. You need to hold it for 10-15 sec until phone restart. I suspect it happened after recent software update since I did not face any issue before that. Hope OnePlus resolve this issue ASAP!! Thanks.
