I used this mobile for a month. I want to share my Experience with it.
Android Version :
J7 came with Android 5.1 Lollipop. But Samsung didn’t say anything About Marshmallow update. This version is good.
Display :
5.5 inch 720p ( 1280x720) HD Super AMOLED Display with 267 ppi. Display was Excellent with Good Colour Saturation & Bright Colours. Basically I’ll Love watching movies in mobiles. I Had excellent Experience with it. Superb.
Performance :
1.5 Samsung Exynos 7580 Octa Core Processor with 1.5 GB RAM. Mali - T720MP2 GPU. Excellent Performance of all Midrange mobiles. I played many Games like Dead Trigger 2, Asphalt 8, Real Racing 3, Wwe Immortals, GTA SA, Modern Combat 5, . It played all games with ease. No lagging at all. Mind blowing Performance. Superb! I loved it. If U r A Gamer. It’s for you. No doubt
Audio Quality :
According to my opinion, No mobile in world is perfect. Audio Quality via earphones was Good. Not Great. Because I am Bass lover. Bass was not that punchy as per my opinion. Another drawback is Audio Output was Low. You can’t hear ringtone, if you are in Another room or in a market. That’s little bit minus.
Cameras :
13 MP Primary Camera with LED Flash & 5 MP front camera with Flash Light ( Remember Not Flash) . Camera performance was Nice. I shooted some videos through it. It came really well. Camera Quality was Excellent.
Storage :
U have lot storage. Internal Storage 16 GB. U can expand with SD card up to 128 GB. another one is OTG supported. That’s really good.
Battery life :
Extraordinary Battery life. Starting Days I got Approximately 4hrs 30 Mins of Screen On Time with Moderate to Heavy Usage. Excellent Battery backup.
Some Of The Cons :
As earlier said, Low Audio Output, Lack of Sensors, Back is little slippery. U must put A Backpouch & Tampered Glass for safety.
Overall It’s Good.
