I have purchased from flipkart 12 jan 15.
I have purchased 8gb in black colour. This phone is very good quality. But this phone have some hang problem
This phone have 1gb ram and 8gb internal memory. This phone is not 4g. This phone have windows 8.1 and very good performance. This phone have snapdragon quad core processor and 4 inch ips display.
And rear camera is very good in 5mp with autofocus and front is not good in 0.3mp. And touch is not good like resistive touch screen. Sound is very good and I play some games and better performance.
