Hi everyone. I have purchased a j3 pro 2 months ago. My opinion about the device is mentioned below
Pros:
Display - It is providing a 5 hd amoled display. I think it is the most attractive patrt of this device. No other competitors are providing amoled display in this price range. But you can get full hd display in this price range.
Better post sale service - As there are more number of service station of Samsung compare to other new smartphone companies you may not harassed for service.
Battery life - Battery life is also average if you are not a heavy user then battery can last upto a day.
4.front camera- its 5 mp front camera is also above average. It can take decent selfies in good lighting conditions. But you will disappointed in low light as there is no flash in front camera.
Cons.
Design and built quality - There is nothing special in its design and build quality. Even you are not getting a metal uni body and finger print scanner.
Rear camera - Rear camera is 8 mp only. And it can take decent photos only in daylight. In low light conditions camera performance is below average.
Processsor- it hanngs some time during multi tasking , snapdragon 430 is comparatively better than this. But phone is not heating very much .
I will not recommend this product.
If you want a non Chinese smart phone then go for it. Otherwise there is nothing special to buy this product.
Thanks.
