Among the best ways to keep your phone secure is with a fingerprint. Phones like the LG G5 come with a fingerprint scanner that allows you and only you to get into the phone. The little fingerprint scanner (that doubles as the power button) is a small pad where your finger would normally rest anyway, so it takes little effort to use.
Let’s get the fingerprint scanner setup on your phone.
Go to Settings and find Fingerprints & security in the General menu
Select Fingerprints and you’ll be prompted on how the process works
Follow the instructions and place your finger on the fingerprint scanner on the rear of the phone
Repeatedly lift your finger and place it back on the fingerprint scanner to provide different angles for easier authentication
