akshaypune , via OnePlus 9 Pro , Oct 1, 2021 : I have a OnePlus 9 Pro (12gb variant) with multiple users enabled. I am using the stock recovery and firmware. I have started facing an issue after the recent update that my fingerprints saved on both user accounts get auto deleted (one or even more fingerprint entries) once or even at times twice a day. It doesn't matter even if the fingerprint is present for both users, it still gets deleted. Is anyone else facing this issue? Could someone help me troubleshoot this? PS: I had taken my phone to the service center, and they asked me to refresh the firmware. I had kept the phone there for an hour and they installed the fresh update, but still facing the same issue.

Restart the phone and set up the Fingerprint once more.

akshaypune , via OnePlus 9 Pro , Oct 2, 2021 : I had replied to them over email requesting for a call back. I had provided my number in the email. Unfortunately I haven't received any update after that.
akshaypune , via OnePlus 9 Pro , Oct 2, 2021 : Thank you for these steps. I followed these steps and now I am waiting to see if the issue reoccurs. It hasn't occurred yet in the last 3 hours after I did the change. I will keep monitoring and keep you posted.
akshaypune , via OnePlus 9 Pro , Oct 2, 2021 : After these many hours, both fingerprints from my secondary account got deleted. And one fingerprint out of the two on the main account got deleted. So unfortunately, this solution didn't work.
Caomhin , via OnePlus 9 Pro , Oct 2, 2021 : Is it possible another user of the phone is deleting the fingerprints? If not and they are auto deleting, there may be a fundamental issue in Android OOS. It would be very hard to pin down the cause. And you may need to go to a OnePlus Approved Service centre again. Or contact OnePlus support directly to see if they have more information on your Fingerprint issue.

akshaypune , via OnePlus 9 Pro , Oct 2, 2021 : I have two separate profiles to keep the work and personal user apps in different spaces. So I am the only user. And even the 2nd fingerprint on my main account got deleted now. I guess I will visit the service center again tomorrow.
akshaypune , via OnePlus 9 Pro , Oct 8, 2021 : There's no response from the support team even after providing them with the logs and screenshots they asked for. Not even an acknowledgment. This really has been a pathetic support experience and I really regret sticking up and even purchasing a product of this brand now. Now for the issue at hand, anyone else got any better ideas? Regards, Akshay.
K1579444125338 , Dec 7, 2021 : I am also facing the same issue. Fingerprints added are auto deleted after some time. Am not sure if this happens once I login to the secondary profile. Not sure if it is due to keeping the same fingerprint name in both profiles. I tried renaming them different in one of the profile. Let me see if it still persists
akshaypune , via OnePlus 9 Pro , Dec 7, 2021 : I haven't faced this issue yet in Oxygen OS 12 Open Beta. I faced this no matter what I tried in OOS 11. Only issue that I have now is after phone is restarted, I need to go into the security settings and disable and re-enable fingerprint to work for screen unlock which is still far better than readding the fingerprints twice or even thrice everyday.
