Been dealing with the blurry Clash of Clans issue since getting this tablet and finally found the Samsung Game Tuner in the app store fixes the issue. Seems to me like Samsung has code written in to TW that caused the issue as here I thought it was Supercell the whole time.
edit: just though this maybe should be in the App section; i'll contact a mod to move it
