I bought Samsung Galaxy E5 2 years back .Now you are thinking that why I am describing it after 2 years when lots of new model and new featured smartphone has come but I personally feel that this mobile is even now best mobile in all mobiles which lies in range of its price.
I bought galaxy E5 in Rs 16000 looks much at that time, little bit I also felt it but after spending some time I feel it is worthy in its price because it never crash apps, hangs and never gets overheat. Still I am using this mobile and believe that I am not going to change my phone even there are many featured mobiles. I love this mobile . It comes with 1.5 Gb RAM and 16 Gb Hd looks less than current smartphones but if you practically use them they will not even be near to the performance of this mobile.
Pros: NO system hangs, no heating problem, looks stylish and slim(7.5 mm), super amoled screen which gives good touch experience
Cons: it is 3g mobile but now perhaps it is upgraded with 4g( I dont know much more about it), 16 GB memory .
