Whenever I'm switching between apps, they frequently quit on me. For example, I'm using gmail then want to go back to Words With Friends and Words With Friends quits unexpectedly. It happens a lot. More often than not. The phone itself seems very slow to me, very laggy. I don't have a lot of apps. There is still space available. The sd card is not full either. It just can't seem to handle anything complex like the GPS. It frequently quits on me randomly while I'm relying it on to get me where I'm going. It also restarts itself randomly even when I'm not using it. It's pretty disappointing. Does anyone else experience this?
