I am using this phone from past 1.4 months. Bought from flipkart. The only disadvantage if the phone is the lock screen button is located in a invalid side & camera has very poor quality on both the side.
Advantage - lenovo brand name , 4000 mah battery, can charge other phobe through OTG cable, Quad core, 2 gb Ram, reasonable price now at rs. 7499. Final verdict- camera lovers should avoid this phone bt good battery lovers.
