Le Pro3 and Le S3 hands-on: Welcome to the U.S., LeEco | Android Central
At a glance, the Le S3 doesn't seem at all like a cheaper phone than the Le Pro3. It has nearly the same dimensions as the Le Pro3, the same quality of screen and a similar metal build that lacks the reflective coating of the more expensive phone but actually feels better to me. Of course LeEco cut back on the internals to hit a $249 price point — a slower Snapdragon 652 processor, along with less ram (3GB) and storage (32GB) than the Pro3. The Le S3 also has a lower-quality screen glass that isn't sculpted as nicely on the edges, and is missing other fringe features like NFC.
Despite the shortcomings when compared to the Le Pro3, the Le S3 still offers a compelling set of hardware for $249, much in the same way that the Honor 5X did earlier this year. You're getting solid internals and a much nicer build and design than most of the phones you can pick up in this price range. From that standpoint, the Le S3 is a bit more interesting than the Le Pro3 that has more competition at $399.
