When setting up your fingerprint, you’re required to place your finger over the reader a series of times to allow for various angles of your fingerprint to be scanned and stored. However, the 6 or so times you scan your finger often isn’t enough for these newer in-screen reader. Especially in mid-range devices like the Z4.

The fix? It’s quite simple actually. Scan the same finger multiple times as a new finger. Each time you can a new finger the reader will store more and more angles of you thumb print, ensuring for a more accurate scan when it’s time to unlock your phone.


Scan the same finger multiple times as a new finger.


I have set up my thumb 5 times on the Moto Z4. After completing this little hack, I went from being frustrated and resorting to pin unlock to unlocking my phone within a second or two!
