since i put the latest update on my iphone 6plus (10.0.2), it has been frequently freezing so that the touchscreen is not responsive. I often times have to do a hard reset three consecutive times to get the phone to become responsive again. Is anyone else having this issue? is there a fix besides just restarting the phone constantly? it has basically rendered my phone useless since it locks up and i cant answer incoming calls. very frustrating!
