Awsome product im using since last year not a single problem brilliant product. It is certain that J7 Prime will get Nouget and even Oreo upgrade. But the time is very uncertain. Personally I and done with those upgrade. I am happy with my J7 Prime do now.
And seriously I am thinking to get a new device in next few weeks. This time it will be not a Galaxy device, but a different one within 15K INR. I have shortlisted some devices and still doing a research
