Starting with the designing:
The designing is created by the Samsung is awesome it is a bigger screen then j7 prime and j7 or J5 and other J series mobile but the processor is changed is now MediaTek instead of and we can see that there is a 4 GB RAM instead of 3 GB is it has a 5.7 inch display which shows that it is a bigger than other mobile the camera is 13 megapixel and front camera is also 13 megapixel it has a new feature in glowing light when an notification or other call can come so it will be indicate that call are coming or notification is entered in mobile
My personal experience is this is the best mobile in this range of a Samsung have deployed sound quality is awesome which is provided by Samsung J series mobile reviews look like a never in other mobiles this time Samsung provide the user interface is an idiot and user can access the all data easily also the style and design is looking killing style other many features in j7 Max makes us happy you will not be disagree from this mobile in the range of 17000 it is the best mobile only difference between is that j7 prime and j7 max is there the RAM of j7 prime is 3GB and the RAM of j7 Max is 4 GB and other difference is that in all Samsung J series mobile has Exynos processor and here Jason Max has a MediaTek processor Indies when other application start and back in the background in fastly recover and other application may be closed but it is also works as a fast app
As we know that Samsung provided the Exynos processor but in these it changed to MediaTek to make a faster processor if I say so there is mediatek processor which is not good in comparison of Exynos because Samsung has a power of a Exynos processor.
Because Samsung only the brand that made the smallest chipset ever which is about a 14nm that other cannot be Beat It
