May be samsung had worked very well to make this phone this is nothing more then a garbage.
Talking about the problum its a complete package of problem. When I baught this phone for the first few days it worked well but when I installed some applications and games it started showing its true color like hanging hand on every heavy app.
Heat up while surfing on net, playing game and on charging.Autometics starting working without even my touch in my pocket and I dont think that some one is in my pocket to use it. So guys please dont waste ur money on this piece of jerk.
