I used lenovo s850 moblie. It was good phone during its luaching time as per other moblies.
In this moblie 5-inch LED display, 1.3GHz quard core mediaTek MT6582 processor and 1GB RAM and 16 GB internal storage, kitket 4.4.2 android version its best perfomance in this phone. And 2200mAH non-removeble battery, 13-megapixel rear camera and 5-megapixel front camera.
Its moblie have some battery problems but otherwise one of the best phone of lenovo moblies.
