The Galaxy J7 (2016) is equipped with a 5.5" Super AMOLED display similarly to its predecessor. As we said in the beginning, the international version has 1280x720 pixel resolution, which isn't great, but is still favored by manufacturers in the lower part of the price spectrum. Even with it, the pixel density is adequate at 267ppi.
As with most of its Super AMOLED devices, Samsung has included a number of display modes. In Basic mode, colors are most accurate, whereas AMOLED cinema, they're notably oversaturated. The middle ground is AMOLED photo.

As is normal for a Super AMOLED unit, the Galaxy J7 (2016)'s screen offers great contrast. The display is decently bright at 353 nits. Tick the Outdoor mode option, and brightness is cranked up to 484 nits.
You certainly won't have problems using the Galaxy J7 (2016)'s display in sunlight. The phone's bright enough and has a 3.756 ratio, which goes up to 3.902 in outdoor mode.
Inside the phone, there's a 3,300mAh Li-Ion battery, which users can replace with ease. The combination of 720p resolution and 14nm chipset manufacturing process promises solid battery life on paper, but we're not ones to go by the specsheet alone.
A few days of testing later, we were nothing short of amazed by the J7's battery life. It achieved more than 18 hours in our video playback test. When browsing the web over Wi-Fi, the result isn't quite as spectacular, but is still great at almost 12 and a half hours. On a 3G voice call the smartphone is good for a full day and change.
All that adds up to an overall endurance rating of 101 hours - an excellent result. It's a resonable 10-hour improvement on the previous generation and some 30 hours on top of direct competitors like the Xiaomi Redmi Note 3 (72h) and the Lenovo Vibe K4 Note (73h).

In a predictable Samsung nature, the Galaxy J7 (2016) is available in single-SIM and dual-SIM variants, so you can get some flexibility in terms of carriers and plans.
Naturally, you get Wi-Fi, but it only operates on the 2.4GHz band, so needless to say there's no Wi-Fi ac support. There's GPS with A-GPS, Bluetooth v.4.0, and an FM radio receiver. NFC is also on board with a dedicated options menu in the Settings.
Wired options include a microUSB port and a 3.5mm jack. The microUSB port can be used to attach an external accessory as it supports USB On-The-Go.
