hope it fixes more than just what has been mentioned.
i have a 16 pro (set up as a new device - not restored from previous iphone) and it has numerous issues.
- camera keeps crashing, only a reboot fixes it until it happens again
- iphone get very laggy, again only a reboot fixes
- one morning i woke up (the phone being on charge using supplied cable and apple charger) and the phone was red hot and borderline non responsive - had to reboot
- randomly alarms don't work - have a daily alarm at 7am, i woke up the morning at 7:30 with the screen showing the alarm had activated (waiting for me to silence it), yet the iphone was making no sound, another morning it didn't activate at all.
- the "find my" widget doesn't display properly - just a white square.
i'm sure i could come up with some other issues if i wait long enough.
