If you have a late-model Samsung phone on US Cellular, odds are pretty good that there's a software update waiting for you. The Galaxy S5 and Galaxy Note 4 flagships are getting an updated build of KitKat, along with the last-gen Galaxy Note 3. Don't get your hopes too high: all three phones will still be running Android 4.4.2 after the update. But Samsung is pushing out a few incremental changes, notably for the dialer and camera.
According to the update notes, a lot of the tweaks are specifically for Google-related services, notably the ability to "search for nearby places and businesses, your contacts, or people in your Google Apps domain." The new builds have Google Hangouts included, complete with SMS integration (not that you couldn't do it for yourself before). "Ok Google" hotword detection is enabled by default in Google Search (again, not that you couldn't do that yourself) and the camera app for all three phones now has touch-to-focus with enhanced controls for focus and exposure. Last and least, all three get an upgraded version of the built-in Google Keyboard with new emoji characters.
As always, expect these updates to roll out in batches, so don't be surprised if you don't see them right away. Samsung hasn't given exact sizes, but since each one is just five apps and perhaps a few under-the-hood tweaks, they should come in at under 100MBs. Galaxy S5 owners will get version G900R4VXU1ANK1, the Note 4 gets N910R4TYU1ANK5, and version N900R4TYUCNG5 goes out to the Note 3. If you've rooted or otherwise modified your phone, prepare for the possibility of failed flashes or lost root permissions.
