Google says it has resolved a bug that caused some 2026 Google Home Speaker units to download unusually large amounts of data in the background, in some cases while the devices were barely being used.
9to5Google reported that one lightly used Google Home Speaker in its own setup consumed 17 GB over 24 hours and 132 GB over 30 days. The same report said another Home Speaker in a different household used only 2 GB in the past month, suggesting the problem is not affecting every unit.
Other reports describe much larger numbers. Android Authority cited user screenshots and posts showing one speaker with a reported 3.3 TB of downloads over 30 days. It also cited a case where a speaker appeared to repeatedly download a roughly 460 MB firmware file every 20 minutes, adding up to about 35 GB a day.
Those numbers are unusually high for a smart speaker, especially when the device is not being used for steady music streaming. They are also large enough to matter for households on capped, soft-capped, mobile, fixed wireless, or satellite internet plans.
Google blames a server misconfiguration and says the issue is resolved
Google initially told 9to5Google on October 19 that a fix was rolling out. On October 22, the company provided a clearer explanation to WIRED, confirming that a server misconfiguration caused some Home Speakers to repeatedly download a software update. Google said the issue had been resolved, although it did not disclose how many devices were affected.
Google’s support material says smart speakers and displays update automatically, and that a spinning white light on the Google Home Speaker means an update is downloading.
As of October 22, 2026, Google’s public firmware page still listed Google Home Speaker (2026) at firmware 3.78.538897 in both its production and Preview Program tables. Google now attributes the bug to a server misconfiguration, so the unchanged firmware listing is not evidence that the problem remains unresolved.
The privacy angle needs care
The word data can sound alarming on a voice-controlled speaker. In this case, the public evidence points primarily to unusual downloads from Google infrastructure, not evidence that speakers were sending comparable volumes of audio or personal data out of the home. The documented concern is bandwidth consumption and update behaviour, not a confirmed privacy breach.
What affected households can check
Google’s support page says the Google Home app can show how much data each device has uploaded and downloaded during the last 30 days on Nest Wifi and Google Wifi networks. The listed path is Home > Wifi > Devices, where individual device usage can be reviewed.
Affected households can compare a speaker’s last-day and 30-day download totals with actual use. The speaker’s firmware can also be checked in the Google Home app under the device’s settings and technical information section.
If a speaker appears to be stuck updating, Google’s update troubleshooting page says the first steps are to reboot the speaker, reboot the router, and factory reset the device if the problem continues. Google also advises contacting Google Home and Nest support if those steps do not fix the update issue.
Those steps do not prove that a unit is affected by this specific bug. They are a way to identify abnormal traffic, gather useful details for support, and reduce the chance that an unnoticed background download burns through a monthly allowance.
A bumpy moment for Gemini in the home
The timing is awkward for Google because the Home Speaker, which hit shelves in June, is positioned as its first audio device built for Gemini. Google’s June product post described the speaker as a device for more natural voice interaction, Gemini Live through Google Home Premium, and 360-degree sound.
Smart-home trust is not only about how well an assistant answers questions. Background behaviour, update reliability, bandwidth use, and visibility inside the home network all affect whether connected devices feel dependable once they are plugged in and left alone.
