After the android 10 update on the A70 device, I can't seem to get my fingerprint sensor working(edit: pardon me, It works but i can't add/remove fingerprints). And if I try to re-add my fingerprint sensor, it gives the error "Fingerprint sensor calibration needed, if this problem continues, contact customer service" I reached out to Samsung Support and we went through steps: 1. Factory reset 2. Wipe cache 3. Safe boot and then trying to add/remove fingerprints None of this worked, sp my last hope was to go back to the place where I bought the A70 device because of my guarantee. I was there today and all they told me quote: "Its not your hardware issue, its just a developer error" I did not know what this means, but the gentlemen said quote: "Wait till Samsung pushes the next update, they are aware of this". So I left with these confusing thoughts. This isn't also that mayor problem, my fingerprint sensor is working, but I just can't add or remove any. I'm not sure what to do next except wait
