If your iPhone can no longer be unlocked with the help of your finer impression, there can be several causes. In this tipps + tricks article, we will give you various aids to solve the problem as quickly as possible.
iOS update as the cause
When updating to iOS 13, many users reported problems logging into apps using fingerprints. If you do not see a message when you open such an app, still try to put your finger on the sensor first. Sometimes the problem can already be solved, because the missing display of the note does not automatically mean that the activation of the app does not work via fingerprint. Make sure that your iPhone has the latest version and update it if necessary.
Add a new fingerprint
If you have set up Touch ID for several fingers, try out the stored fingerprints in different positions. The error may only occur when a particular finger is imprinted. If so, add the faulty fingerprint again. In our step-by-step guide, we'll show you how it's done:
1st step:
Open the settings of your iPhone and go to " Touch ID & Code ". 2nd step:
Then tap on " Add fingerprint ". Finally, you will be asked to hold your finger in different positions so that your iPhone can completely capture the imprint. You can then lock your smartphone and test whether the error has been resolved. What else can you do?
It sounds simple at first, but make sure that both the sensor and your fingers are free of grease or dirt. Freshly applied cream or moisture and sweat can, for example, falsify the measurement of the sensor and thus lead to Touch ID no longer working properly. You can also clean the sensor with a clean, lint-free cloth to remove dirt..
Touch ID still not working?
If the measures presented so far are unsuccessful, you should go to an Apple Store with your device or contact Apple Support .
