Will a case leave discoloration on a tablet? Uncategorized June 1, 2021 Forums AndroidCentralLeave a Comment on Will a case leave discoloration on a tablet? I just took my tablet case off and there appears to be black burn-looking spots on the back of the tablet. For reference I have a 10.5 Samsung tablet with a blue back. The case was black and it has not been taking out of the case since purchase. Sharing is caring!
