My iPhone is starting to do some quirky stuff. Delays on gestures, Phone calls not disconnecting, not pairing with various BT devices like it used to. These dont happen all at once just random on random days. No pattern. It's not like I can predict when one of these will happen. Phone also seems much slower opening and changing between apps. For instance, The text app will open but it can take 2-3 seconds for the keyboard to show up. After the 10.2 update Siri has become more ignorant than before. Names she used to get are now so far off I'm wondering WTF is wrong with the system. Is it possible that a restore will fix some of these things? should I wipe the phone and restore from backup or is that just a waste?
