Last week I received a tablet from (you guessed it) China, with a great big smudge (newton ring) right in the middle of the screen. I really didn't want to go through the hassle of returning it so I try my own fix, and it worked. I applied a suction cup (one I bought at Harbor Freight) to the screen right over the smudge and gave a very slight tug. Removed the cup and the smudge was gone. Now I know you naysayers will tell me it's STILL IN THERE and i agree, but for now I CANT SEE IT. So problem solved. Hope this helps others with moisture collection.
