There are several mobiles of lava. Iris 400 is one of these. I used this mobile . I have a poor experience of this set .
The battery performance is not good. The ram of this set is 512 which is backdated now a days. In the case of front camera is very bad picture quality. External memory should be supported 64 g.b instead of 32 . When I did some work on online it did not give satisfaction.
So I would recommend to compare market in this price before purchasing .
