Not sure if my PlayBook has become defective. I cannot turn it on from sleep mode by swiping up from the bottom bezel. It use to work when I first got it. Now it does not. Sometimes it will turn on if I swipe from left to right but not from down to up.
Anyone else having issues. This is a great feature but useless if it does not work. I hate to press the ridiculously small power button.
Have you tried rebooting to see if that fixes things? Press all at the same time the (ridiculously small) power button and both the Vol Up and Vol Down buttons.
Take it back and exchange if you're still in that window. If not have RIM replace it.
I would go with this solution. I have never had my PB do that. No matter what, swiping a finger across my screen, not even fully, wakes my PB from sleeping. It sounds defective to me, especially if a hard reset won't fix it.
