Samsung galaxy J7 is a good phone which you can rely on. It has very good features like it has 5.50 inch screen, it has 1.6Ghz octa-core processor with 2GB RAM. Its internal storage is not too good, it is only 16GB. Its operating system is not the latest but quite good i.e Android 6.0.1 . Its camera quality is stunning. It has 5 megapixel front and an amazing 13 megapixel rear cameras. Its battery is 3300mAh which is not at all good for all of its features. Its resolution is quite OK because it has only 720x1080 pixels of resolution. Thank You.
