I'm been using my gen 1 iPad Air for a few years, and it has rarely given me problems. However, a couple of days ago i noticed my tablet automatically turn the volume up. I tried to turn it down, but it turned itself up again. I have to hold the volume down button to make it stop. And it keeps on doing it at random times and it's very annoying. The same situation happened to my tablet about a year ago, and it eventually went away within a few hours, this has been going on for the past couple days. I don't know if it's the tablet or the iOS. Please help!
