I bought my S8 in May and have had no issues until a couple weeks ago when it started freezing every other day or so. The first time it froze on a home screen I took it to U S Cellular. They restarted it by holding volume down and the power button simultaneously for 7 seconds. Since then it freezes at random times but never when I'm actually using it. It was froze this morning when I woke up. I am technology challenged and know this problem could be caused by any number of things. I looked but couldn't find any similar threads. I really need some help and ideas to solve this freezing issue. Thanks!
