Hi! It suddenly fixed itself after I learned how to hard reset it and did so repeatedly around 4-5 times. I’ll check if it goes back to headphone mode after a while. If it doesn’t, I’ll be fine I think , but if it does, I’ll probably have to get a professional to take a look.
The icon on the volume bar are some overhead earphones, no bluetooth, although I do use bluetooth headphones and have never used wired headphones on this iPad until today while trying to fix it. Also when I try switching from headphones to iPad speaker, there is no iPad speaker option, as I have tried that aswell.
I suspect it was either debris on the headphone jack, or interior damage. It couldn’t have been water damage because I do not recall splashing anything other than the screen with water, even then, that was months ago.
