I have same problem ,mate . Still I have no solution . Samsung is a cheat . They gave experts SD variants for review . Experts gave us a awesome review . Then they gave us exynos variant . Which is just a portable heater . Some brand sell same device in defferent name but Samsung sells different device in same name . Totally dissapointing . Samsung makes more money selling exynos variant . Because they don't have to buy SD .
I bought every note but this is my last purchase from samsung . Soon I will go for oneplus or Huawei .
