Some users have reported what appears to be moisture under the screen of their new Galaxy Tab 10.1s. Android Police has attributed this phenomenon to Newton’s Rings – “interference pattern caused by the reflection of light between two surfaces.”
It appears that this problem is not very widespread. I for one have not experienced it. The cause of this is heat. So if you ever do experience it, then you can toss it in the refrigerator for 10 to 30 minutes.
Have you had this problem? Let us know in the comments or the forums!
