Airplane mode on iPhone 15 keeps switching off
I travel a lot and have had multiple iPhones, never experienced this before current trip.
iPhone 15 / iOS 17.4.1
This is what happens: get on flight, use corner shortcut to click on airplane mode button / button turns orange. Then within a minute I get the green notification that I have voicemail (I never listen to my VM), and within seconds the airplane icon top right is replaced by 5G or whatever. This on repeat, just cycles round. I’ve tried going into settings and clicking airplane mode there, same thing. I’ve hard turned off, thought I’d fixed it but it came back.
I’m wondering if it’s like sometimes on my Mac it won’t shut down because something is trying to complete an action. Could it be some buggy app? How would I identify it? It’s really annoying as I like to use my phone inflight (music, games, downloaded content), but had to keep turning it off so in the end I just hard turned off until we landed. I’ve had this phone for a year and done multiple flights with no issues. Any ideas?
