Another day, another Jelly Bean update to a Samsung Galaxy device. Today's target: T-Mobile's Galaxy S Relay 4G (I still hate that name). Unlike many of the other Jelly Bean updates rolling out to Galaxy phones, this one's only available through Kies and OTA.
In order to grab it, you'll need to be on the latest official firmware, have at least half the battery remaining, and the latest version of Kies. The T-Mobile support page also recommends that the device isn't rooted (big surprise there).
If you meet those requirements, fire up Kies or head into Settings > About phone > Software updates to get your taste of Jelly Bean.
