The Samsung Galaxy S8 and S8+ are a set of lucky devices as they are receiving the latest Android 8.0 Oreo updates. Though Beta, owners of the two phones get to test the Oreo based Samsung Experience 9.0 before anyone else. Earlier last month, Samsung started rolling out Android 8.0 Oreo Beta for S8 and S8+ with firmware build versions G950USQU1ZQJJ and G955USQU1ZQJJ. The update came to a select number of users registered under Samsung’s Oreo Beta program in USA, UK, and Korea.
Although only S8+ users on T-Mobile, Sprint, unlocked network carriers can only receive the update, it seems that AT&T is seeding the OTA zip files for all. Using the OTA updates available for the S8 and S8 Plus, you can update almost any Snapdragon variant to latest Oreo build ZQK1.
As of now, not much is know as to what’s new with this new Galaxy S8/S8+ Oreo Beat 2 ROM. However, soon the global variants like SM-G950F and SM-G955F can benefit from the same Samsung Oreo Beta 2 upgrade.
