My iPhone 6 Plus running 9.2.1 won't update Apps, won't open some Apps, the battery drains quickly and it won't show me if there is a Software Update when prompted.
All of a sudden it seems I'm having trouble with my phone. Apps won't update (that's when I notice something was wrong), some Apps won't open, when I go to Settings and check for Software Updates the wheel spins until it times out with no answer. Also the battery seems to be draining quickly. I'm not sure if I have any malware, although I'm very careful...only download Apps from the App Store. Any advice? I'm hopeful 9.3 tonight will take care of these issues, but is something more going on...I don't know. Thanks.
