I have use this phone . It is a one of the best phone in this range. 5.5 inch display. 13mp rear camara and 5mp front campare to samsung or other company is not good and the meager draw back is battery is 2500mah and the heating problem is also.so the thease are the issues. but I must say phone batter than other. internal memory 16GB good and RAM 2GB is also good.
In this phone also good for playing heavy loaded games at all.
And the other funcnality is sound quelity is very good and android latest version 6.0 marshmallow was supportes good product.
