Hello all. I have looked around the net, but can't seem to find an answer to this, but... I have the 10.1 GT-P7510, running 3.2 which is rooted. I've had it for a while and it's a great little machine, but I noticed a problem the other day. I usually have it in a closed cover, why I've never noticed it before, but, the other day, I had it open, I put it in standby and on my desk. I then noticed that the screen comes on to the lock screen for about 5 seconds, then off again, on again about 20 seconds later, off again and so on! With random presses of the standby button, it doesn't do it all the time, but I have now noticed it's doing it a lot. Which is draining the battery pretty quickly. Any one else had this issue or know what might be causing it? PS...I have a Galaxy S2 on ICS rooted, with all pretty much the same apps on it and that's never done it, as far as I know.
