My wife and I have Identical Samsung Galaxy Tab 10.1 GT-P7510. I upgraded both to Android 4.0.4 Kernel Ver 188.8.131.52 Build Number IMM76D.UELPL. They both freeze more often than they did before the upgrade but my real problem is that her's won't play imbedded videos such as those in Facebook. She can click on the link and You Tube opens if it is a You Tube video and it plays. On mine I can click on the video and it plays just fine. Hers worked until the upgrade. I think it is associated with the Flash Player though I can't find a difference. Does anyone have any suggestions?
