I got a PS vita which seems to be playing up. I can turn it on but it seems like the PS Button along with the rest of the buttons don't respond. However, if i hold down the power button for about 10 seconds or so it will reboot into the Safe Mode which i can then control using the D pad and regular buttons. If i launch a game, none of the buttons will work and the ps button/power button does nothing. Seems like such a strange problem. I've checked on YouTube and have removed the back to clean out the power button, but that didn't help at all. Anybody have any suggestions?
