I bought Sensation a few weeks ago. I really like the phone. However, I downloaded a game, Innotia 3 recently. While playing the game, I experienced the phone freezing twice already. During those two occasions, I could not restart the phone or anything. I had to remove the battery to turn it on again. Has anyone experienced this also? What should I do? I do not know if it is the game or the phone which has a problem.
