AT&T has released the Android Oreo update for the Samsung Galaxy S8 and S8+ on their network, becoming the last major US carrier to do so. Verizon, T-Mobile and Sprint have all released the update, with Verizon being the first.
For those of you on AT&T, if you have the Galaxy S8, you are looking for build G950USQU2CRB9. If you have a Galaxy S8+, build G955USQU2CRB9 is your jam. In both cases, the updates come with the February Android Security Update patch and both updates come in at just over 1.5GB in size. That means that downloading over WiFi is a must.
