Okay here what happened…
I accidentally dropped my iPhone in water (2 secs in water) it was in a case. I immediately shut the phone down, and stuck it in a bowl of rice (with the case off). After about 8 hours I recharged the phone and turned it back on.
Everything is working fine, Internet, music, sound, screen… Everything EXCEPT YouTube videos just say "loading" and does nothing further. Note: this occurs in the YouTube app.
Any feedback will be greatly appreciated.
