HiroHamada4337 , via OnePlus 8T Aquamarine Green , Oct 23, 2020 : Even JerryRig described this problem in his Oneplus 8T video. I didn't believe it. I bought oneplus 8t and I'm having the same problem. The fingerprint sensor isn't working properly. It says the screen is dirty or the finger is dirty even though I try many times to set up my finger print lock. I think it's the only bug I have noticed in oneplus 8T apart from oneplus 8 pro display issues i have heard about. Fix this bug in the next update please. Side note - Also please try to lower the prices of atleast the screen protectors. 1290/- for a Glass Screen Protector for oneplus 8t is really costly.
