Lock Screen Instantly Turns Back Off?

[TerryMasters]

Does anyone else have this problem? I'll hit the power button/let it go into standby and when I wake it up, the screen comes back on and instantly turns back off. If I hit the power button again it comes back on fine (sometimes it turns off a second time but 3rd time usually works) and I can unlock it and use it. But the first time I go to unlock the Tab it always turns the screen back off a second afterwards.

I noticed similar behavior on the Best Buy store display model. Turns out there was a "Retail Mode" that the tablet was running in that caused this. Once this mode was disabled the Tab behaved normally. Is it possible your Tab is in this mode?

I have no idea, is that a Power+Volume Up thing?
