I have a new A70 with the latest patch and also got my OH an A50. Fingerprint scanner is practically useless on both these devices (in any real world scenario), shame, otherwise great phone. I worry that software updates won't help the situation, as perhaps it's the underlying technology.
Hi, I am also facing the fingerprint issues with Samsung A70. I have even factory reset my new phone, but the issues remains the same. Fingerprint works only occasionally, and it is not very smooth. Sometimes, it simply does not work. I have also removed the tempered glass, but still it does not work smoothly. I am very disappointed and thinking to sell it.
I was having the issues regarding the finger print sensor not working properly. I have made certain changes. I have removed the tempered glass and replaced it with TPU film protector. Secondly . While registering finger prints, I registered there fingerprints but by slightly touching the screen. I would suggest don't apply force while registering your fingerprints. After that I also disabled the transition effects of the biometrics and enhance the touch sensitivity. After restarting the phone it is working with well and smoothly.
I genuinley hope it's fixed for you, but you may also be experiencing what I have, that the day you re-record your fingerprints, it seems to work well (or well enough), but then this degrades over coming days (and doesn't work in real world situations, coffee shop etc). Good luck!
I removed my glass screen protector and am using it without anything right now. Just took me 8 attempts to unlock with fingerprint. Screen is beautiful without a protector
