How To Disable Fingerprint and Facial Recognition on Your Phone

How to Guarantee Your Phone’s Fingerprint Reader Works Every Time
The fingerprint reader on your iPhone or Android phone always seems to fail enough on the first try. It can be anything from your fingertip not fully covering the sensor, wet hands or possibly the phone didn’t get an accurate read when you first registered your fingerprint.
By registering the same fingerprint more than once, you’re increasing the chances of your phone capturing enough data to unlock the first time. That’s because when you register your fingertip in the phone settings, it isn’t always clear which parts of your print the software has captured. A somewhat helpful animation or audible feedback will urge you to lift your finger to capture more area, but that doesn’t necessarily reflect the data your phone’s actually storing.
