The mobile phone I have buyed has giving me a pain my neck. Totally loss of money it was never expected by samsung, it is totally cheats for buyers of this phone, the phone was fully functioning like old galaxy models camera only in writing form of 13 megapixel but its work like vga camera. The screen of the mobile phone keeps on going black after every 2 hours. Poor sound quality, standard android features not available that are available in other phones, flooded with samsung apps. I cannot operate my mobile for 2 hours when it turned black neither switching off and off mobile phoneworks. Not at all worth for even 7000rs. Waste of 15000rs. For my experiance I suggest you not to buy this phone.
