If you’ve got a carrier-locked Galaxy S25 series phone, you can manually check for the update by heading to Settings > Software update. Unlocked models haven’t received the update yet, but we expect they will soon. Samsung should also publish more details about the included security fixes in the coming days.

If your smartphone has been lagging or no longer holds a charge for all-day use, today is a great day to upgrade while the Samsung Galaxy S25 Ultra is hanging out at $1,067.99 — the lowest price Amazon has ever offered.
