One UI 2.5 has arrived on more versions of the Galaxy S9, S9 Plus and Note 9. Following the arrival of the OS update for unlocked handsets last month, One UI 2.5 has now reached the T-Mobile and Verizon locked editions of the three devices in the US. One UI 2.5 for the three carrier-versions also includes the October 2020 security patch update, but the November 2020 set has already hit the Note 9 in Germany.
