I received my Sony Tablet S this past Monday 5 December 2011 as a Christmas gift. I opened it up to set it up so it would be ready to go on Christmas day. I processed the upgraded for Android 3.2.1 and have not been happy since. I experience issues where alot of apps "force close" which isn't the most annoying problem (since I have a Droid phone, I'm used to that). Every so often when the Tablet is not on the charger, the backlight of the screen dims to the point where you cannot see anything. It's not off because I can still access different screens, but in order for it to come back to full brightness, I have to press the power button to "sleep" it and then press the power button again to wake it up. Then it's back to full brightness. This happens in all sorts of apps while I'm actively using the Tablet so I know it's not the screen saver timer. I pressed the reset button, but it still does this from time to time. I called Sony Support and was not given any help because they have no idea what the problem is. I've been researching over the net to see if there are similar problems to no avail so I'm posting my own in hopes of finding a solution. I love the Tablet and want to keep it, but this annoying issue is causing me to consider another tablet. Please help!!!
