    after a week of always working, out of the blue my phone stopped recognizing my fingerprint. Added and readded my fingers and thumb. restarted my phone nothing is working.

    Does anyone have an idea how to fix this

    Possible update? Nu screen doesn't go light up when I use the scanner (it previously did) I didn't change any settings. Even reset my phone still not working.

    Ok I can get it to work but only if I use the ambient display. It takes 3 or 4 tries and then it unlocks... @OnePlus please fix this

    If you have recent system updates the try rebooting and redo fingerprints. If you just put a aftermarket tempered glass screen then it might have compromise sensor.

    I still have the official screenprotector from OnePlus on it. Had a system update a fee days ago and then it gave me no problem.

    Mine is perfectly fine but there is still a hit and miss sometimes, new technology under the screen maybe humidity plays a factor too. Anyways phone is 100 percent, I find turning on face unlocking is better and way faster when access to phone. Support will probably get back on you and hope all is well.

    I hope so. For now I did enable face unlock. Still a bit sad, the fingerprint scanner under the screen is so cool. But we'll have to wait for an update I guess

    There was a fingerprint guide by Oneplus i read some time back. they said if you are facing issue with reading. Try removing all the registered prints. Reboot. Re-Register the prints in complete darkness. And finger print registration has 2 parts.
    part-1: different angles of centre area
    part-2: edge reading
    so place finger appropriately as per the parts

    Restart to recovery mode by pressing power +volume down key
    Clear cache.
    Try re adding fingerprints by deleting existing.
    Mine fingerprint was working even without face unlock disabled

    Hey guys, i found a fix for this. I tried clearing the cache from recovery mode, even factory reset, but those didn't help.

    A sure fix for this (i tried it two times and it worked) is running a fingerprint calibration test. Enter engineer mode (dial *#808#), do the calibration test and it fixes itself. You don't need to delete the fingerprints, it works with the old ones.
