Sometimes, when I use the fingerprint scanner the light shows up anywhere but under my finger, so I can't get into the phone unless I use the side button to turn it on and off. Also, sometimes the screen dims, while in use, and only the menu buttons work, which is very annoying when I'm in one of many a forum complaining! I've used the device troubleshooting stuff and it got the all clear. I check for updates throughout the day and restart the phone at least twice a day. I never let it go below/above 15-85 percent. This is a recent problem. I think I've had this phone for a year.
