I use this mobile 1week & I found this is very good at low price. I purchase only for 4g uses. But this mobile has some merits and some demerits. This mobile looks awsome. Screen is nice. Processor is nice at this price. Ram is also nice but required 2gb almost. Both sim slot is support 4g which is good.
Battery backup is superb. Smart glow is jabardast.
In my mobile the camera quality is very good at day time but at night time camera is not perfect. Selfie camera is not good. 5mp camera but I think not good. In s4 mini the selfie camera is 2mp but quality is superb. So camera quality is average. Display is amoled but in hd video some time black portion is look like graphics some time. So I think in this price tis is very nice phone. 4g support is good.i love it.
