I bought this phone and used it for almost 1.5 years. The phone has 5 inch screen, 16 GB internal memory, 720 X 1280 resolution and 2 GB RAM. I must admit it was the worst experience using this phone. Some of the issues that I faced were:
The phone heated up a lot even after playing a game for 10 minutes
There was lag in the working just after 6 months of purchase
The battery backup is not good. It barely lasts a day with moderate usage
NO ANDROID UPDATES JUST AFTER 6 MONTHS OF USE
All in all it is not the value for money. I would recommend looking for other brands in the same range.
