I have tested this phone personaly, and some results are decent whereas some are excellent.
My experience with this phone is good. I like its camera quality, there is flash on front camera also so its a good thing next moving to its processor, its a 1.6 ghz octa core processor made by Samsung exynos and its quite good processor, I would say the gaming on this devoce is also good but I you are hardcore gamer than its not for you my dear. Battery is also excellent
