I have a Verizon Samsung Galaxy S5 (SM-G900V) with Lollipop V 5.0. Ever since I updated to Lollipop, my phone will randomly start switching at 1-2 second intervals between the Home screen and my Wallpaper for sleeping. I cannot get it to stop switching back and forth by pressing any button. The only way to get it to stop switching is to restart the phone.... if I can catch it in between switches. I went to the Verizon store to see if they could fix the problem and the Tech said to shut it down and remove the battery for a minute or two and then reinsert battery and restart. We did that and it seemed to work for the rest of the day. Then it started doing it again, so I did the same thing... remove battery and restart. This is not a permanent fix. Also, and this may be related, sometimes the Home button does seem to do anything whether I am in a Browser (Chrome), EMAIL or some other application. Could these be related to some of the bugs mentioned in the other forums about the Lollipop 5.0 update? Thank you for any insight or help.
