Summary: I chose two stars because I guess I didn't "hate" it. It didn't work well for my needs. I had something to compare it to because I had an LG phone that worked great. The Samsung kept dropping it's connection to the bluetooth in my car. It would connect and disconnect whenever it felt like it. I never had that problem with my LG. It also dropped calls constantly when I wasn't in the car. Again, I didn't have that problem with my other phone.
Summary: I bought this phone used saying it worked great and tested for functionality, but it freezes multiple times a day to the point where you have to take the battery out. It also does a split screen, seems like the phone gets confused when you open the slider and splits the screen in 2 and then it freezes like that. Phone is attractive and other than those things is nice. I'm hoping I can find a firmware upgrade for it.
