Samsung likely has more devices to update than most smartphone manufacturers, and as such, they’re constantly pushing out updates to their never-ending list of handsets. Sometimes these are bigger updates—like a firmware update to Android 5.0 Lollipop—but more often they’re just very minor version bumps to fix bugs and close minor security holes.
SamMobile keeps track of all of these updates to Samsung’s handsets, and their latest list of recent updates includes firmware spanning Android 4.0 all the way to Android 5.0.2. Devices include the Galaxy A7, Galaxy Core Prime, Galaxy Ace 4 LTE, and more. Many of these are updates to devices in international locales, but at least one, the US Cellular Galaxy S6 Edge, is for a United States device.
