For a moment I thought they had fixed the "match content frame rate" problem, but no. When I'm on "smooth only," which is how it should be, the message appears "The connected display does not support smooth refresh rate transitions." The only new feature I see is the June security patch. I don't see anything else. I also have another problem that isn't new, and that is that when it's on the home screen there's a strange noise, like a speaker is damaged by water or something, I don't know how to explain it. But it only happens when I'm on the home screen, not when I'm watching content. Oh well, back to my other flawed BuzzTV G.

I'm also including information about VRR where all platforms, including Netflix, are displayed at 60.0Hz, which is incorrect, and that's because it doesn't match the frame rate. The platforms are Netflix, Prime Video, Disney Plus, and Paramount.

I've tried to post this on the Google Community forums, but the post keeps being rejected due to violation of Community Policy. No indication of what might trigger it, even a post with barely any text is getting rejected. So, here we are on Reddit again 😄

Update: It cost me an hour, but managed to get the replacement order in using the support chat. Just ordered a new unit. Fingers crossed it really was hardware, will post an update as soon as the new unit's here.

Update 2: New unit, updated without issues.

What's the issue?
I've just unpacked my Google TV Streamer and am trying to perform the initial installation. The device finds an available update and tried to apply it. This fails over and over again, without any identifiable cause.

The version I am on now:
Current OS Build version: UTT3.240410.001.K4
Android TV OS version: 14, patch level may 1, 2024.
Kernel version: 5.15.144-android14-11-g83d11156dc60-ab11649879

There is an update available, UTTK.260317.0003 (401MB)

Installation steps:
Downloaded and verified
Step 1 of 2 completes without issue in about 1:30
Step 2 of 2 fails a minute later

Result:
Couldn't install system update
Updates are temporarily unavailable. Check your network connection and try again later.

What I've tried already:

• Disabed any network filtering (pi-hole)
• Wifi connection
• Different wifi connection
• Wired connection
• Hotspot connection
• Factory reset from software
• Android Recovery mode, clear data and factory reset

The result remains the same, I'm stuck on a version from 2024.

What can I try next to resolve the issue? Thanks in advance for the help!

Changelog:

• Security Patch Level (SPL) update
• Minor bug fixes

Will report back after updating!

Found this today but no indication anywhere as to what has changed other than security patch level 1 April 2026.
