This sounds like you have a hardware or software issue on your phone. make a backup (if you aren't using icloud backups already) and then make a genius bar appt. and see if they can fix this. I have never seen that level of glitchy-ness on an iphone without there being a serious issue. either on my own phones or during nearing a decade in IT.

Yes, I have a hardware and a software issue: the root cause is that it's an iPhone running iOS as normal.

This isn't a hardware defect or a broken install. It's just mediocre software, nothing more. This isn't even that glitchy. All those things don't usually happen at once, although they are recurring - including for friends on different device generations, ruling out unlucky hardware and moon rays.

I agree with parent. You phone is broken, my friend. In the years I've been using iOS, these have happened to me less than a handful of times. Definitely not something I would ever remember if not prompted.

Man, software occasionally erroring out.

That eliminates...nearly all software ever created. Good luck out there
