Why does my phone says fingerprint hardware not available

It is a less aggressive step than resetting to factory settings, but it will still erase any traces of configuration in settings or applications. Now all that remains is to uninstall the latest ones and repeat the process to see if everything returns to normal. If the fingerprint works correctly, it is that some app is the culprit. Then we tap on accept for the mobile to restart in safe mode. We can do it by keeping the power screen pressed and holding “Turn off” when it appears on the screen. The best thing in this case is to enter Safe Mode to check it. This occurs when permissions have not been granted or the app is using them in an abusive way, blocking the reader for our use. We have installed a third-party game or app that is causing the fingerprint sensor to malfunction. Now it only remains to check if the fingerprint works correctly again. Then we tap on “Free Up Space” and choose “Temporary Files” then click on delete and restart the device. To do this we will have to enter Settings / Storage and tap on the internal storage. Clearing the cache partition works well for the fingerprint sensor to work properly again. Sometimes it is the accumulation of temporary files, which can corrupt the proper functioning of those who depend on the fingerprint sensor. Whether it is a fingerprint sensor on the screen or on the back, you just need to wipe it dry from time to time to remove these remains and make its effectiveness as it was the first day.

This can cause errors and we think that the reader has failed. The passage of time can cause a thin film of fat to be generated between the sensor and our finger, which prevents the correct reading.

Dirt is always the enemy of our mobile, and it will not be less in the fingerprint sensor.
