Just popping on here to say, I too have this issue. And if it is indeed because of Bluetooth being enabled, that is absolutely ridiculous! Just because I have a smart watch, doesn’t mean I don’t want to hear notifications sounds on my phone when I get messages! And if we have to turn off Bluetooth in order to hear notification sounds, what is the point of buying an Apple Watch!?!
I also have issues with the camera. Macro mode is garbage! The camera app won’t focus on the subject in macro mode, so the pics are blurry. I DID just learn of a work around for that, kind of, but the pics still turn out a bit “noisy” and pixilated. Also, when I tried to record video at a concert, after 15 seconds the entire camera app freezes, and I have to force close the camera app, and restart it again, only to have it freeze up again after another 15 seconds.
Both of these issues started happening immediately after I got my 14 pro max on release day, and continue even though I am keeping up to date on software updates.
iPhone quality has seriously gone downhill in the past several years
