I have s20 ultra in the USA. Usually the phone performs well but overnight when I try to unlock it in the morning it doesn't allow me to unlock using fingerprints or faceid both are deactivated at that time. I know that after updating os or software, this happens as I am samsung galaxy for 10 years or so but this is completely new to me. I have checked that all my apps are updated in play store, os is updated. Then I factory reset the phone and tried to open it in safe mode but it doesn't work. I purchased it from best buy and after 14 days, I can't return the phone. Please help.
