Query: It freezes alot. That's it!

I'm realy satisfy of the overall features. but, It freezes 5,6 time a day after turning on the device. I cooudn't even turn it off! I have to take the battery out and then try it over. I don't know, maybe I have to update the firmware. I'm trying to figure it out.
