Delete and reinstall game?
It is very difficult to give advice with such vague perimeters
Which Samsung tablet? Galaxy? Galaxy A series? S series? what number?
"Up to date on all updates' means very different things depending on what tablet you have, Samsung have nearly 30 different tabs
"plenty" of storage is relative, does it mean 2GB or 160GB
