LG G5 is one of the best smartphones released in this year so far and no one can deny it. Thanks to its features and new look, the device has won its popularity around the globe. Today, I want to tell you that I first liked the LG G5 fingerprint scanner. It’s fast, very accurate, and extremly easy to setup.

Things are supposed to be great as you practically don’t have to mess with any passwords or patterns to unlock your device. That’s how you can set it up for the first time:

Go to the Lock screen and security in the Settings;
Select on Fingerprint and then +Add fingerprint;
Follow the instructions until 100% of your fingerprint has been scanned;
You should also setup a backup password;
Select Ok to Enable Fingerprint Lock;
Now, to unlock your phone, simply hold your finger on the Home button.

However, things don’t always work as they should and the Fingerprint Scanner has its issues. It might stop working out of the blue, or you might be getting a lot failed attempts, but here’s what you can do in such a case:
