Samsung SCH-A950

I've only had this phone for about 18 hours and am debating whether or not to keep it, or trade it in for the A970. The keys on the A950 are really small and difficult to press, and I don't like the fact that the backlight and the front LCD go black while on a call. I don't intend on subscribing to V Cast (such a waste of money), so maybe the A970 is a better option? Or are these things standard on all Samsungs? Any feedback is welcomed. I'd rather not go through the hassle of returning this, so if you can convince me to keep it I will!
