According to GFXBench, the Samsung Galaxy J7 (2016) will feature a 5.5-inch display, carrying a resolution of 1080 x 1920. While the screen size is the same from the OG model, the resolution is getting a bump from the 720p that the phone sported last year. The Snapdragon 615 chipset remains under the hood, carrying an octa-core 1.5GHz CPU. 3GB is on board, double the 1.5GB of RAM that was found on the OG Galaxy J7. And 16GB of native storage remains on board.
The Samsung Galaxy J7 (2016) will still have a 13MP rear-facing camera and a 5MP front-facing selfie shooter, just like the OG model offered. Last year's model also came equipped with a 3000mAh battery, and we would expect about the same for the 2016 version of the handset. Android 5.1.1 will be pre-installed on the Galaxy J7 (2016).
