Slow performance? Restart your device. – Solitaire by MobilityWare Review

I love this app, but I was also experiencing the problem where the game pauses at startup. The initial animation with the card suits freezes, and then when the game starts, you tap a card, and nothing happens for about 5-10 seconds. After the game finally responds to the initial card tap, it works as normal until you go away and come back much later, at which point you get the freezing card suit animation again. I fixed this by shutting my phone down completely and restarting it. After I did that, the game worked much better.
