When I play brick breaker on my 7100i the gameplay is choppy. I was wondering if anyone else had this problem, and if so how do I fix it?

Chet,

I have the problem too. I have assumed it was the result of incoming messages using some of the device's resources. Sometimes, the breaks in movement cause me to overshoot the ball with my paddle.

Do you suffer from tendinitis from playing the game?!

I think it has to do with the wireless connection also.

The choppiness actually got worse when I had the sim card out of my phone. The phone kept roaming, trying to find a connection or something.

The wireless connection consumes a lot of power, so make sure you have a good battery that is fully charged.

Try playing the game when it is plugged into the USB charger and see if it makes a difference. It did for me...
