SAMSUNG GALAXY J7: I talk about my user interface I am using it more than 2 months. This phone is good it have octacore processor, 1.5 gb ram, 16 gb internal storage, 13 mp rear camera and 5 mp front camera with front facing flash, 5.5 inch screen.
This phone have only 1.5 gb ram but it is sufficient for it because its optimization is very good it doesn’t lag like other samsung phone this phone handles heavy games easily. Its camera takes decent picture because it have 1.9 adapture.
Talking about its build quality and design; its a very slim phone and have plastic peel off back cover and silver side panel. it have 3000 mah battery capicity which gives you all day long battery backup if you are a normal user if u are a heavy user it last long for 10-13 hours if you use it continues.
Overall it is good phone I recommend you to buy it.
That’s all.
