Step by step

Open Software update
Open Settings and scroll down to Software update. The page shows your current version. Ours showed One UI 8.5 when we took these step pictures; on 16 Oct 2026 our Galaxy A57 updated to One UI 9.0, and the One UI 9 notes on this page show what moved.
Done
Check for updates
Tap Check for updates. If the phone is up to date, it says so. We did not download anything.
Done
Install now or schedule it
When an update is found, the phone downloads it and offers to install it now or at a time you choose, such as overnight. Our phone had no update waiting, so we cannot show that screen yet.
Done
If the update fails
Samsung suggests freeing space (uninstall unused apps, or Device care, Optimize now), backing up, and trying again. Clear an app's cache only, never its data.
Done

If you do not see this option

Your Galaxy runs One UI 9. Software update shows only a big One UI 9.0 and a Check for updates button. Auto download, Software information and Last update are now in the three-dot menu at the top right. On our Galaxy A57 the last update was One UI 9.0 (Android 17, version A576BXXU6BZIE, 2315.25 MB) on 16 Oct 2026, with the security patch still 5 Sep 2026.
Galaxy A57 not updated to One UI 9 yet? Since 12 Oct 2026, SamMobile and Sammyfans report that some Galaxy A57s get stuck on an error screen during setup after the One UI 9.0 update. Owners say restarting into Safe mode, then restarting normally, got them past it; Samsung has not published a fix. Our A57 is on that update. To wait, tap the three dots, Auto download and pick Never; ours was set to Using Wi-Fi only. Samsung says critical updates may still download over mobile data.

Your phone came from a carrier Carriers release updates for the phones they sell, so the timing follows your carrier. Samsung adds that a phone unlocked from its original carrier may need a SIM from that carrier to download updates. Source: Software update failed on Samsung device

If this does not work

The update stops downloading Samsung says you can resume the download from its notification. If it keeps failing, you may be able to install the update from a computer with Smart Switch, which offers it when the phone is connected by USB. Source: Software update failed on Samsung device
There is not enough storage The phone shows how much space the update needs. Free up that much, for example by deleting apps you do not use, then try again. Sources: Software update failed on Samsung device, How to troubleshoot software update issues
