After the restart, return to Settings > System > Software Updates and install the build offered there. Beta software can include new features still being tested and known regressions, so use the same channel selector to return to Stable if you need the supported production channel.
What changing the SteamOS channel does
The channel selector controls which SteamOS system builds your Deck is offered. Stable is the normal production channel. Beta and Preview are test channels that Valve uses for features still being evaluated. Valve’s Steam Deck News release notes can list known issues and may tell affected users to switch back to Stable when a change causes a regression.

This is a system-software choice, not a separate game installation. You do not need to reinstall SteamOS to opt in, and changing the selector does not require a factory reset. The change takes effect after the restart requested by the Deck, then the available build appears in the regular Software Updates screen.

Stable, Beta and Preview compared
| Channel | Update maturity and risk | When features arrive | Known-regression likelihood | Returning to Stable |
|---|---|---|---|---|
| Stable | Production channel intended for normal use | After changes have moved through testing | Lower than test channels, but any software release can still have issues | Already on the standard channel; select Stable after using another channel |
| Beta | Test software with new features still being tested | Earlier than Stable | Can include known regressions listed in Valve’s release notes | Use Settings > System > Beta Participation > System Update Channel > Stable, then accept the restart or update prompt |
| Preview | Test software with new features still being tested | Earlier testing stage than a production release | Can include known regressions listed in Valve’s release notes | Use the same channel selector and choose Stable |
Valve’s release notes establish that Beta and Preview are testing channels; they do not provide a universal numeric risk rate. If your Deck is needed for uninterrupted play, Stable is the conservative choice. If you want to evaluate a feature before it reaches Stable and can tolerate troubleshooting, Beta or Preview may be appropriate.
Before you opt in
Read the current release notes
Open the Steam Deck News page and find the current SteamOS Beta or Preview entry. Read the list of changes and the known-issues section for the channel you intend to use. Notes are dated and change over time, so do not rely on an old version number as a permanent description of the channel.
Decide whether test software fits your use
- Choose Beta when you want earlier access to features and accept that a recently shipped change may cause a problem.
- Stay on Stable when reliability matters more than early access.
- Use Preview only when you specifically want the earlier testing stream and are prepared to return to Stable if a release note identifies a regression.
Prepare for a restart
Finish anything you are doing on the Deck before changing the channel. The opt-in flow requires a restart, and the subsequent system update can also restart the device. Keep the Deck where it can complete the on-screen update process without being interrupted.
For Valve’s general software information and troubleshooting guidance, keep the Steam Deck Software Info & Troubleshooting Guide available. The official Steam Support instructions for the channel change are also documented in Steam Client Beta (including Steam Deck steps).
How to install SteamOS Beta updates
1. Open the Steam menu
- Press the physical Steam button on the left side of the Deck.
- Select Settings.
- Open System.
Valve’s support wording is: “If you are using a Steam Deck: Press the ‘Steam’ button; Select ‘Settings’ then ‘System’; Navigate to the ‘Beta Participation’ section; Expand the System Update Channel pull-down and select ‘Beta’; Follow the prompt to restart your device.”

2. Select the Beta channel
- Scroll to Beta Participation.
- Expand the System Update Channel pull-down menu.
- Select Beta.
The menu may look slightly different after a SteamOS revision, but the relevant controls remain in the System settings area. Select the label currently shown for System Update Channel, rather than looking for a separate “SteamOS beta” application.
3. Accept the restart
- Follow the prompt to restart the Steam Deck.
The restart is part of the channel change. If you dismiss the prompt, the Deck may remain on its previous channel until you accept and complete the restart.
Recommended Free Tools
4. Check for the offered build
- After the Deck restarts, open Steam > Settings > System.
- Open Software Updates.
- Check for the offered build and choose the install or download action shown on screen.
The exact button label depends on what the Deck has available at that moment. Use the action displayed by SteamOS to download or install the update; do not assume that selecting the channel alone has already installed a new build.
5. Confirm that the update completed
Let the Deck finish the update and any requested restart. Then return to Settings > System > Software Updates and check the channel and update state shown by the interface. Compare the installed build’s notes with the current entry on Valve’s Steam Deck News page so you know which changes and known issues apply to the software you are running.
What to expect after installing a Beta build
Features may arrive before they are polished
Valve describes Beta and Preview releases as updates with new features that are still being tested. Early access is the reason to use these channels, but it also means that behavior can change between releases and that a feature may have a documented limitation.
Known issues are part of the release notes
Read the issue list for your installed release instead of assuming every problem is unique to your Deck. A release note can identify a regression and recommend Stable as the practical workaround. Keep the dated entry bookmarked because the issue list is tied to a particular release and can change when Valve publishes another build.

Do not treat the channel as a performance promise
Valve does not publish one guaranteed percentage for battery life, performance or failure rate across all Beta or Preview builds. A particular release may fix a problem for some users and introduce another for others. Use the release notes and your own workload to decide whether to remain opted in.
How to switch back to Stable
Use the same selector
- Press the Steam button.
- Choose Settings, then System.
- Open Beta Participation.
- Expand System Update Channel.
- Select Stable.
- Accept the restart or update prompt shown by the Deck.
After restarting, open Settings > System > Software Updates and install the Stable build offered there. The wording of the controls can change between SteamOS revisions, so follow the labels visible on your Deck rather than relying on a screenshot from an older release.
When switching back is the right response
Switch to Stable when a Beta or Preview release introduces a regression that affects your games, controls, connectivity or general use, especially when Valve’s release notes identify the same issue. Returning to Stable is the supported practical response described in those notes; it is not a reason to erase the Deck or reinstall the operating system.
Troubleshooting the Beta update process
The Beta option is not visible
Start from the exact path Steam > Settings > System > Beta Participation. The selector is inside System Update Channel, not in the game-download settings. If labels differ, look for the channel pull-down under Beta Participation and use the current wording shown by your SteamOS version.

You selected Beta but no update appears
- Accept the restart prompt if it is still pending.
- After restarting, return to Settings > System > Software Updates.
- Check again for the offered build and use the install or download action displayed there.
- Review the current Valve release-note entry to see whether the build you expect is available for your channel.
Channel selection and installation are separate stages: selecting Beta changes the stream, while Software Updates presents the build that is currently offered.
The Deck becomes unstable after the update
First install any system update that is available and restart the Deck, following Valve’s Software Info & Troubleshooting Guide. Then check the release notes for a matching known issue. If the notes identify a regression, return to Stable through Beta Participation > System Update Channel and accept the restart or update prompt.
A restart did not resolve the problem
Do not repeatedly change channels without checking which build is installed. Record the channel shown in System settings, read the corresponding dated release notes, install any offered system update, and restart once more. If the problem remains and the release notes do not identify it, use Valve’s troubleshooting guide for the next supported steps rather than treating a factory reset as the default response.
You want to test again later
Remain on Stable until a later Beta or Preview release addresses the issue that made you leave. Before opting in again, read that release’s changes and known issues, then repeat the standard seven-step channel procedure. This lets you choose a specific testing window instead of staying on a problematic build indefinitely.

Match problems to the dated release
When reporting or troubleshooting an issue, note the channel and the release-note entry that applies to the installed build. “Beta” is a moving stream, not one permanent version. A problem listed for one dated entry may be fixed, changed or replaced in the next entry.
Use Valve’s own documentation for changing labels
The Steam Support instructions provide the official path, while the dated Steam Deck News entries provide version-specific context. Valve’s Steam Deck booklet is additional device documentation, but the live settings labels and release notes take precedence over a static booklet when they differ.
Common mistakes to avoid
- Looking in the wrong menu: the channel control is under Settings > System > Beta Participation, not the library or per-game properties.
- Skipping the restart: the channel change requires the prompted restart before the new stream is active.
- Assuming selection equals installation: after restarting, open Software Updates and use the offered install or download action.
- Using an old version number as a guarantee: Beta and Preview builds change, and their issue lists are tied to dated release notes.
- Ignoring a documented regression: if Valve recommends Stable for the issue you are seeing, switch channels instead of continuing to troubleshoot a known problem on the test build.
- Expecting a universal risk statistic: Valve does not publish one percentage covering Beta or Preview failure rates and performance impact.
Frequently asked questions
Do I need to reinstall SteamOS to join Beta?
No. The supported method is the channel selector in Settings > System > Beta Participation, followed by the requested restart and the update offered in Software Updates.
Can I return to Stable without erasing my Deck?
Yes. Select Stable in the same System Update Channel menu, accept the prompt, and install the Stable build offered after restarting.
Are Beta and Preview identical?
No channel is guaranteed to have the same build or issue list. Valve groups both Beta and Preview as test releases with features still being tested, while the dated release notes explain the specific changes and known issues for each entry.
Where can I see which problems affect my build?
Use the dated SteamOS Beta or Preview entry on Valve’s Steam Deck News page. The current notes are more reliable than a fixed list copied from an older release.
