While Samsung's newest flagship, the Galaxy S9, is just hitting the market, last year's flagship, the Galaxy S8, is getting some love, too. Samsung and its US carrier partners are finally upgrading the Galaxy S8 to Android 8.0 Oreo, a version of the OS that came out six months ago.

Verizon, T-Mobile, and Sprint are all pushing out the update now, with no word yet on updates for the AT&T or unlocked US version.
