fingerprint issue

Go setting > display > touch sensitivity ON.

a50's FP scanner was never fast to begin with, which is stated in EVERY review there is on the internet, always do research on a phone before buying it. although the scanner is improvable via software updates (but that doesnt mean samsung's willing to do that). if you want a faster option you'll have to use face unlock for now

Try adding the same finger twice. For eg, of you use your right thumb frequently add right thumb twice in your phone and add your left thumb once. Its an old school technique which improves the dectection a little.

one of the worst sensor..horrible. xiaomi was excellent. Samsung finger s***

one of the worst scanner..takes 3-4 attempts and it works at the same position after many attempts..horrible , even entry range phones has better scanner
