I happened to buy Lenovo a7000 in dec 2015 when I bought it. at the beginning, I did not face any problems but when I use to go for high graphics gaming it uses to lag.
Then after 1 month of use I started facing problems with the touch left part of my screen would not respond then I started facing the problem with the camera it would capture blur images. The battery use to drain so fast. So all I could do is sell it I sold it for 3000 on olx. So I suggest you guys buy any other phone instead of this.
