Ive got chance to use j7 for few days and with my experience I can say its really nice smartphone buy Samsung under this well Budget Price range
Design-j7 design is very Similar to j5 one can say its a bigger version of j5, Body is made of Plastic but its from good quality nand Looks Premium
Performance-J7 got 5.5inch big screen With Hd Resolution and Comes with dual Micro Sim card.
It supports 4g on both the Sim and thats a Plus point
Storage nand Os- J7 comes with 1.5GB Ram and 16GB Internal Storage but u can also Load it With Micro SD card, Apps can Installed in Internal Storage but u can move it To Sd card
If we talk about OS It comes With Lolipop 5.1.
Processor and Camera- J7 Loded with 1.5GHZ Coupled with Mali T-720GPU Which can handle Most of yourd Hd games and Videos. Now if we talk about Camera Its got 13MP Rear and 5MP Front Camera and both performes well but Low Light Images Wont be that good, However one uniqe Feature J7 has its its has Flash light on both Sides which will help you to take Good selfies under Low Light.
And last it Comes with 3000mah battery Which is Sufficient for Make it Run for One day at full use. So, Over all we can say its a really good and Competetive phone under this Price yes you Still Get some batter deals with other company but With J7 you get a brand Samsung.
