The fingerprint scanner on the galaxy s6 is definitely a cool feature on this device. Setting it up takes about a minute. What you want to first do is go into the settings then lock screens and click on fingerprint scanner. You then need to tap your finger down about 10 times until it says complete. Now there are a couple issues I have when using the fingerprint scanner on the galaxy s6. The problem is that when it works it works very well. Often times however I find it doesn’t work very well, and can be very frustrating to unlock your phone. With that said the galaxy s6 fingerprint scanner is a cool feature but your better off using a simpler lock screen theme like the password or pattern options.
