After a month long love affair with my BlackBerry Playbook, taking it for a tour of Asia, it seems to have caught a bug! Malaria? Psychosis? Dengue Fever? Don't know.
It was charging in another room, while I was on my desktop computer. Suddenly I heard a piano playing. The Playbook was playing a one note song on the piano ap. It wouldn't respond properly to a swipe, but just switched randomly to other applications without my touching the screen. After fighting with it - trying to close aps as they popped up, I got to the Favourites menu and all icons were quivering. More aps opened randomly. I shut off the BBP but it popped back on and continued misbehaving, like it was possessed by a demon. After several more tries to shut it off, I succeeded. A full reboot seems to have cleared out the demon, for now. Anyone seen this behaviour? I hope it's not a Cracked Berry.
Seriously, this happened to me after I had my PlayBook for a month last year. Nothing I did could fix it (let the battery drain, move away from cell phones,etc). I sent it to BlackBerry to fix...they sent a new one back. Haven't had the issue since.
