May as well! By the time Samsung ever gets around to rolling out Android 15, Pixel devices will probably be getting Android 16.
Beta testers have been on Beta 3 for six weeks: Samsung just released Beta 4, but it's a compatibility test for carrier-branded devices. That means carrier S24 Ultras have the February security update, while unlocked phones have January's. One UI 7 is a fantastic upgrade from 6.1 - as botched as this beta test seems, though, many of us testers feel that the delays are inextricably linked to low sales figures for the S25 series (oh by the way: I understand that Samsung is charging a restocking fee for S25 returns if users are dissatisfied).
