Since the launch of the Steam Deck, Valve has been hard at work polishing its Arch-based Linux distro, SteamOS, for both its own gaming handheld and, more recently, third-party gaming handhelds. With the launch of the SteamOS 3.7.15 update , Valve has taken steps to correct a handful of gaming handheld issues. Most of the updates are bug fixes and quality of life updates, rather than new features, but there are also a number of security updates included that patch out known CVEs. This follows recent news about the official full release of the new Steam Store redesign and the Steam beta that adds support for detecting Secure Boot and TPM states for modern anti-cheat solutions. Overall, Valve seems to be working towards getting SteamOS in a state that is both user-friendly and stable in an attempt to attract and keep as many users on its platform as possible.

For the Steam Deck, the clock and power limits and Wi-Fi connection should more reliably return to their configured states after the device wakes from sleep, and the battery charge estimation has been improved. Wake-on-Bluetooth support has also been returned to all versions of the Steam Deck with support for BLE peripherals—which should prove handy when the handheld is docked. The built-in screen reader also now has multi-language support, and there are a number of audio improvements. For starters, the Steam Deck's volume will no longer jump to 100% when removing wired headphones, the Deck will now also automatically switch to USB audio devices when detected, and audio distortion in the built-in microphone has also been removed. Valve has also removed the Pro Audio profile from the KDE desktop mode—an anti-feature many Linux users will be aware of because it simply disables audio when you select it.
