This is crap.it hangs tooo much.it has made my life hell.i cant even play a simple game on it.and about the battery.worst battery capacity.it always gets hot whenever plug into charger.even in just 6 or 7 months the touch is not working properly.and the style is also very boring.the reliability also very bad.the features is also not good.the name is galaxy.but is not even a simple star yet.and moreover the sound quality.sound is very low.although it is very product dont buy it plzzz.
