Key points
- The update applies only to the Chromecast with Google TV (4K), not the HD model.
- The Android Security Patch Level advances from October 2025 to August 2026.
- Google notes general bug fixes and performance improvements in the release notes.
Google is deploying the first software update of 2026 for the Chromecast with Google TV (4K) model, according to a report by 9to5Google. This release arrives eleven months after the previous version was distributed to users. The update brings the Android Security Patch Level to August 2026, moving it forward from the October 2025 baseline that was previously active on these devices.
In plain English
This update is specific to the 4K version of the streaming stick. The HD variant of the Chromecast with Google TV does not receive a new release today. This is notable because both streaming devices are typically updated simultaneously when new software drops. The release notes from Google indicate that the update includes "other bug fixes and performance improvements" alongside the security patch level bump.
The background
The Chromecast with Google TV has been a primary streaming hardware option for Google users. Maintaining regular security updates is critical for connected devices that handle user data and network access. An eleven-month gap between releases is longer than the standard monthly cadence often seen in consumer electronics, though the source material does not explain the delay. The update version is identified as UTTA.260813.002 in the release notes provided by Google.
What changes now
Users with the 4K model can manually check for and install the update through the device settings menu. The path to the update is Settings, then System, then About, and finally System update. Once installed, the device will reflect the August 2026 security patch level. There is no confirmed fix for any specific vulnerability mentioned in this release, only the general patch level advancement and performance tweaks.
What to do and how to stay safe: Google
- Manually check for system updates on your Chromecast with Google TV (4K) via Settings > System > About > System update.
- Verify that your device shows the August 2026 security patch level after installation to ensure you have the latest protections.
- Keep your home network password strong and changed regularly to reduce the risk of unauthorized access to connected streaming devices.
- Monitor official Google support channels for future updates, especially if you own the HD model which did not receive this specific release.
