How about Samsung gt-s5820?

I'm using it. Very good, watch TV for free, have wifi, the configuration is enough, and the software under MM is free of traffic charges. 2.3.6 The system is particularly powerful. I used it for several months and found that the only drawback was that the camera could not focus automatically. As for memory, because it is a 2.3.6 system, a lot of software can be moved to the memory card.
