Samsung j7 is good Android mobile to use for.
Great features like front camera 5mp camera with flash.
And rear camera 13mp which gives you a great pics capture with led flash.it has great led display which gives you a brighter and clarity.
But internal memory is less in this mobile.it has two defects; you will miss lots of call due to low volume and also lack of internal storage memory.
All the above its a good phone to boost your standard
