Yes...You must see the SoC... Samsung uses either their in house Exynos or Snapdragon SoCs, in some few phones like J2 2016, J7 Max, On Max, they used Spreadtrum SC9830, Mediatek Helio P2o( or P22, I forgot the model no ) respectively. So they are bogus phones. Because of proper software optimisation of Samsung, they are running without any hiccups. Personally I owned a J2 2016 which is 2.5 Years Old and no problem. Currently I am an user of A7 18 and that J2 16 is used by my mother.
