Problems

My phone's screen recently became garbled when I would text somebody and an email notification would come through. Also I would text a friend and have music playing in the background and then the song would cut out and jump around and play a different song. Is anyone else having problems like this? Should I go back to the Sprint Store and b**ch at them? I told them my problems last time but they checked everything out and said that if I still had problems then I would have to come back and they might just have to order me a new phone.

I just got me a new one. It was the end of the day and the tech people were tired so they gave me a new phone. I also used my old samsung to take pictures of the problem i was having. They didn't want to give me a new phone but I previously took it to the other one in my area. It's working great so far and I still have the plastic on it. Did anybody buy the invisible shield yet?
