I have tried clearing my cache, I've tried taking apps off in safe mode. I've done just about everything I know. I've not had any damage to the phone either. Thank you
I had, and now have again, the error you describe on my LG G3. I got it to work last time, but I don't recall how :-X. I did the usually recommended items with no luck, including factory reset. If I figure this out again I will let you know.
