Google TV Streamer update unlocks a major hidden upgrade for your smart home setup

• Google has rolled out the UTTK.260317.003 build for the Google TV Streamer, marking its first major OTA update of 2026 and upgrading it to the April 2026 security patch level.
• The update quietly brings Thread 1.4 support to the device.
• A new “Share Thread network credentials” setting allows users to generate a secure local QR code on their TV screen, eliminating the frustrating process of connecting third-party devices.

Google is finally giving the Google TV Streamer some long-overdue attention. After sitting on a stale October 2025 build for more than half a year, the streaming box is receiving its first major OTA of 2026.

As spotted by 9to5Google, the 219MB UTTK.260317.003 build updates the Google TV Streamer’s system to the April 2026 security patch level, clearing up a massive backlog of security vulnerabilities.
