I have used this phone and happy to say that beside of a mediatek processor it is a quite good phone. It is powered by mediatek helio x23 processor which is a 10 core processor , 4000mah battery , stock android , dual camera . It is a good device as their is lot of improvement in this phone. Its camera quality is good only for single shots. In portrait mode the phone doesnot detect the object and background i.e it blurred background with object. For Single shots it is quite good. Selfie camera is 13mp with flash which is very good. Its problem is that it is too heavy ( 180gm) to keep it in pocket. There battery easily last for 1 days or more according to your usage.I had played asphalt 8 it played well but their is some framedrops.It has 4gb of ram which handle multitasking easily.So I hope you understand and take the rigght decision to buy this device or not.
