Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
And I use it to play my video music. What I liked most was it was new, and the price was excellent. Not the latest ..... sure, but for me that's just fine. There's not a scratch on it, and it runs perpectly so it's trouble free. I also have to admit, it's the best Phone I've had yet.
