My friend is using Samsung Galaxy E7 a week now. I have also used his phone, I would say Thank you Samsung for good phone, here are few points
a) Mobile display is super amazing HD fantastic display.
b) 2 GB Ram
c) Smooth touch - when I say "smooth" I mean it
d) Amazing Sound Quality
e) What you need more - Voice Quality, guess what you will get a superb Voice clarity on calls
f) Speed- Whatsapp/bookmyshow/hike/facebook opens like wind.
g) Camera- Excellent 13 MP camera, different modes are superb and you can take nice pics at night also
h) Front camera- 5 MP will make you selfie freak if you are not.
i) Ultra slim- easy to carry & looks quite proffessional
There are lots of other qualities, I cannot describe it. I have just used it 2-3 time, I would say use it from your friend or from circle & I am sure you will be liking this as well.
