Samsung Galaxy S3 1.2GHz Dual Core 4.8inch MTK6577 Android 4.1 16GB Phone
[CEC_ACP_A162]

Are the specifications real as written on the screen, I mean MT6577 1,2 GHz, 1GB RAM, 16 GB ROM, 8MPx and 1,3 MPx cameras? and does the GPS work properly?
Is the phone in stock and shippable as soon as I place the order?
Which upgrade can be done, Android 4.1 ?!?
Which is the manufacturer?

Thanks in advance for your kind reply
