Did you know by changing these two settings you can improve the fingerprint unlocking speed as well as not reading issues. Well I found out and tried it, it does work accurately and fast as well. After the one ui 4.1 update I faced a bit difficulty getting to read the under display ultra sonic fingerprint reader in my N20ultra even after reregestering the finger print several times, then I discover a faster and a convenient way to unlock it faster as well.
So why wait try this method and see
It should work for all fingerprint supported devices.
