Hi everyone , I used this device for 6 month . From the first day . It was so slow in working even without installing any third party application in it. As I install few apps it got worse . It comes with 512 mb ram which is not a appropriate space . It has got quadcore processor but still as the ram is in less amount. Processor can't do any thing. Its sound quality is bad. Phone's rear camera is a 3.2 mp camera. Which takes worst photos. Its look is bad .it is a heavy device . The battery backup last upto 4-5 huors as it got 2300 mAh battery. But still it is a low cost device.
