You can watch the video on Cambo Report YouTube channel. It is quite informative, too, showing us the phone’s camera features as well as user interface. Here is what I have learned after watching the video (and then looking for info online, since I cannot speak Korean):

– lack of Bixby assistant,
– Briefing feature, a new page entered by swiping right on the home screen. Briefing collects all the latest news and social media updates for you to check out in one place,
– 13mpx dual rear camera, 5mpx selfie shooter,
– Live Focus, feature that allows you to adjust the depth of field before taking a picture,
– app shortcuts, feature that can be accessed by press-holding the app icon. It allows you access to some of the application’s actions without starting the app itself.

That is all, unless I missed something. Other than dual camera, video shares with us none of the device’s specification. Judging from earlier leaks, phone will come with a 5.5 FullHD screen, Exynos 7870 CPU, 3000mAh battery, 4GB RAM, 32GB ROM and more.

We do not know Galaxy J7 Plus’ exact release date, but we may have to wait for it until 2018.
