So my iPhone 7 Plus is the 125gb, it works fine when left pretty empty. But when I fill it with Music & Videos; (which I love having movies on it) the iPhone don’t sync anymore with iTunes. My music & videos say they’re being sunk but just ends up GRAY on my iPhone. So I have to RESET this iPhone & delete all contents & settings to get it to talk to iTunes again. What’s the point of the extra space if it can’t figure out how to use it without getting all retarded talking to iTunes? Am I doing something wrong? Do folks move Movies a lot without trouble? I need help cause I’m getting sick of re-setting this thing! All the time!
