I have been using Samsung j5 prime for more than 1 year and till now I have never experience any hang or other problem.
It had a good shape and fecilitate with finger print and high clarity camera . I feel it had a good display capability, because thousand time it had fallen from me till now there is no problem. when we compare to other phone there will be mass hanging while ubdating but j5 prime will not disturb us with this bad behaviour.
