Having some issues with my z fold 3 5g. Sometimes the screen freezes. A few minutes later it will un freeze. Other times it won't turn on at all when I open it, but will if I wait a few minutes. Yet other times when it comes back on it's rebooting. In all cases I can still receive notifications and music will play via you tube music through wifi. This is getting more frequent and more annoying. I have cleared the cache, thinking that may be helpful...nope. Help!
