For the last six years, I've been Android but have decided to come back to iPhone. I'm finding my iPhone 7 to be very buggy and wondered if this is normal? Some of the issues I've had: - Camera sometimes not loading (it seems to try a couple of times and then settles on a blurry frozen shot) - Screen not responding to taps for several seconds - When trying out the different ring tones, the volume graphic will periodically appear, even though I've not touched the volume buttons - "Sharing" a video to iMove just brings up a black screen - Opening Pages brings up a dialogue box "Sign in required. You must be connected to wi-fi to download them." Sign in to what? Download what?! I just wanted to open Pages to write something. - When the keyboard is open, I can't swipe up to bring up the menu with brightness etc. There's other, but this is all I can remember. Is this normal? I've always been told Android is buggy, but I never had any real issues compared to this iPhone 7.
