Review: Samsung Galaxy S Lightray 4G for MetroPCS
The Galaxy Lightray ships with Android 2.3.6 and a light user interface treatment from Samsung and MetroPCS.
The overall feel of the menus is near-to stock Android. There are seven home screen panels for customization and plenty of MetroPCS widgets and apps plastered on them. The main app menu is a grid that slides left and right rather than up and down. Samsung has given the app icons the "Samsung look." The default view is an alphabetized grid, though the grid can be rearranged to your own liking or shifted into a list view.
The settings and controls are standard for an Android device and allow users to make a wide range of adjustments to the Lightray's behavior. Wallpapers, ringtones, and all that are easy enough to change, though there are only a handful of widgets available and none of them are all that appealing.

My biggest gripe is that there aren't any lock screen shortcuts.
Performance was quite good, thanks to the Exynos3 1GHz processor. I didn't notice any problems opening apps or shifting from app to app.
