I've run into a weird bug that either turns my volume up to max or turns it down to mute. Whenever I have my phone in my pocket and I want to change the volume, I kind of press the buttons on the side with a bit of luck. However, it sometimes happens that I press both buttons very shortly (milliseconds) after each other, triggering this bug.
In some way, the phone turns the volume up or down continuously, no matter if you press a volume button, it will always go to max or mute again.
Now, I've figured out that restarting the phone fixes this, but I was wondering if someone else has noticed this and if there is a fix that doesn't need restarting. As far as I know, this only happens under iOS7, never noticed it before that.
Edit: Almost a year later and one iOS-version later, I am STILL noticing this bug once in a while. Still haven't found a way to replicate it.
