Did they start offering the Exynos Note 3 last year? From what I noticed, with the S3 and S4 they 1st offered Exynos due to S3 only coming in Exynos internationally initially with the LTE coming later in the year, with the S4 they 1st got Exynos due to Samsung only bringing Exynos into SA but later brought Snapdragon, after that with the Note 3, S5 and Note 4, they seem to stick with Snapdragon only.
I don't think so, only the Snapdrizzle fo shizzle.
S3 they sold only the Exynos version initially, and that has no LTE (still have mine). They brought in a different S3 with LTE shortly before (or after) the S4 was released.
Anyway, the point is they bring in only 1 model, sometimes the Snapdragon, sometimes the Exynos. Ever both at the same time.
