Google rolls out first 2026 update for Chromecast with Google TV (4K)
The build bumps the Android security patch level to August 2026 for the 4K device, while the HD variant receives no new release today.

Key points
- Build UTTA.260813.002 is currently rolling out exclusively to the Chromecast with Google TV (4K) model.
- The update advances the Android Security Patch Level to August 2026, moving from the previous October 2025 level.
- The HD variant of the streaming device is not included in this release, breaking the usual simultaneous update pattern.
Google is deploying the first software update of 2026 for its Chromecast with Google TV (4K) streaming device. According to 9to5Google, this release arrives eleven months after the previous version was issued to users of the hardware.
The update, identified as build UTTA.260813.002, is currently being rolled out specifically to the 4K model. Google’s release notes indicate that the HD variant of the Chromecast with Google TV is not receiving a new release at this time. Historically, both streaming devices have been updated simultaneously, making this staggered release an exception to the standard schedule.
Security and Performance Changes
This software update bumps the Android Security Patch Level to August 2026. This represents a jump from the previous patch level of October 2025, which was the last security baseline for the device. The source material notes the time gap but does not specify the reason for the delay.
In addition to the security patch, Google notes the presence of other bug fixes and performance improvements in the release notes. These general improvements are typical for major firmware updates but are not detailed further in the provided documentation from the vendor.
Installation and Affected Hardware
Users with the Chromecast with Google TV (4K) can manually check for and install the update through the device interface. The process requires navigating to Settings, then System, followed by About, and finally selecting System update to download and install the build.
The HD variant of the Chromecast with Google TV remains unaffected by this specific rollout. Owners of the lower-resolution streaming stick should not expect to see build UTTA.260813.002 or the August 2026 security patch level on their devices at this time.
What should you do?
Users with the 4K model should verify their current system version to determine if the update has arrived. Those who have not yet received the push notification can manually check for the update using the steps outlined above. HD model owners should monitor future announcements for their specific hardware variant, as no fix or update has been confirmed for their device in this release cycle.
What to do and how to stay safe: Google
- Check the system version on your Chromecast with Google TV (4K) to see if build UTTA.260813.002 is available.
- Manually trigger a system update check via Settings > System > About > System update if the update has not installed automatically.
- Verify that the Android Security Patch Level shows August 2026 after installation to confirm the security baseline is current.
- Monitor vendor communications for updates regarding the HD variant, as it was excluded from this specific release.
