I saw many phones getting hang in lock screen and need to hard restart with volume - and power button together pressing... And i have issue with the A50 on screen finger print as well... It automatically unlocked while in my pocket... Now i use only face unlock some time it doesn't work
Sure, Samsung promises software updates that will supposedly improve the fingerprint scanner’s responsiveness and accuracy, but whether that will indeed be the case is questionable. The only thing left for you is to keep your phone up to date and hope for the best. Changing or removing the screen protector could also be helpful, but I honestly doubt it’s the main reason for the slow fingerprint scanner.
