I have had the same issue with the X. Mine was just replaced so maybe this one will be different but not sure. I may have noticed it reconnects, but don’t remember. If Apple can get this fixed and there’s tons of evidence it’s better than the A1865 X, I would be tempted to upgrade due to the camera but as of now, I feel safer staying where I’m at. My X takes amazing pictures so it’s definitely not a big temptation. It would be nice for Apple to fix the reconnection issue. My 7 Plus did the same thing.
You’re probably smart to hold off for now. Seems like a lot of people still having issues. Be interesting to know if your replacement handset fixed the issue.
When I set up my max, I set up as new, because I wanted to make sure I didn’t have any leftover jailbreak files. It’s a pain in the butt, but it does rule out a lot of things. I haven’t read this whole entire thread, so I may have missed it, but for the people having this issue, did you try setting up as new?
