Hello everyone I bought samsung galaxy e7 on 15 April 2015. I am using it and still I did not face any problem. This is one of the best product I am using from the brand samsung. It have 2 gigabytes of ram, for this reason it never get hanged or lag.
Camera quality is also very good. For multitasking this is one of the best phone available around 18 thousand. You can go for it without any concern. Love this product.
