Hi guys, I've been having some trouble with my iPad Mini lately. Let me explain. The volume locker worked great until a few weeks ago: when I press the "+" button, the volume goes up. Great. The thing is, when I press the "-" button, the sound completely mutes, even if I was at maximum sound. Anyone knows how to fix this? I tried everything. Thank you! edit: as pointed out by a fellow MacRumors member, a SINGLE press mutes the device, not holding it.
