It will take days or weeks for the rollout to complete. If you want it before then, you can download the OTAs and sideload them from here: https://developers.google.com/android/ota
Hasn't Android had a thing for a while where it gives update priority to people who manually check for updates? Like, my phone (7a) didn't say an update was available, but then I clicked the "Check for update" button, and now it said Android 14 is available.
So I don't think anyone who really wants the update soon needs to sideload the OTA, just check for an update and you'll probably get it.
I always do that. I think I only waited once, it notified me like 4 days later.
But when I go into the settings and manually search for the update, it always gives me the update as soon as it's announced.
I got my phone unlocked directly from Google, but I think it might still get held back based on my network. I'm not sure what the current state of this is. Historically at least, yes, it's been a clusterfuck with US networks.
