VoiceOver changes what a tap does, which is why you cannot reach Settings. Learn the two gestures first, or just ask Siri to switch it off.
The old phone is not being emptied, so starting over is free. Apple supports a wired transfer that skips the failing wireless link entirely.
An empty backup list does not mean your data is gone. Apple leaves photos, messages and notes out of backups because they already sync to iCloud.
A web page cannot count anything on your iPhone. Apple calls these fraudulent adverts and tells you to close the tab rather than run anything.
Apple files this symptom under battery issues, not charging issues. A wireless pad and one settings screen tell you which part to replace.
User Busy is a telephone network code, and the standard says the network can send it without the person you called ever knowing you rang.
Nobody has broken in. Apple documents five separate reasons for that one label, and only the carrier-network version is worth acting on today.
