Pixel 11 owners are getting another September software update, but it still is not the Android 17 QPR1 release many users have been waiting for.
Google is rolling out build CD1A.260905.001.B1 to the Pixel 11, Pixel 11 Pro, Pixel 11 Pro XL, and Pixel 11 Pro Fold. The release follows the CD1A.260905.001.A1 build that reached some devices earlier this month.
The newer update is less than 100MB for some devices, with 9to5Google reporting downloads of around 97MB. Google has also published factory and OTA images for the B1 release, giving owners a manual installation option.
For owners, the practical takeaway is simple: install it when available, but do not expect the visual changes and other additions anticipated with Android 17 QPR1.
What the update does — and doesn’t — change
The most important detail is what the update does not include: Android 17 QPR1.
Pixel 11 devices remain on the initial Android 17 release, while several visual changes expected with QPR1 are still absent, according to 9to5Google. Google has not yet announced the stable QPR1 rollout or its accompanying Pixel Feature Drop, although both have been expected this month.
The September patch level is also unusual. The first update carried a Sept. 1, 2026 security patch rather than the expected Sept. 5 level, which 9to5Google had expected for the monthly release.
Why Google may be doing this
The lack of a detailed changelog makes the reason for two September releases difficult to pin down. 9to5Google suspects the first update was a hot patch for problems discovered after the Pixel 11 series launched, while Android Headlines points to reports of app crashes, Wi-Fi problems, and display behavior issues among early users.
Those reports don’t show that this update fixed any particular bug. Android Headlines also notes that Google previously said a Video Boost audio problem would be addressed through the Google Camera app rather than this system update.
The timing, however, is telling. Google appears willing to push maintenance software separately rather than wait for QPR1. That could mean the company is treating early Pixel 11 stability issues as something that needs attention before its next major software release.

What Pixel 11 owners should do
For most owners, checking Settings > System > System update is the simplest approach. The newer security patch is a sensible reason to install the update when it appears, even though Google hasn’t disclosed the individual fixes.
Owners shouldn’t install it expecting new Android 17 QPR1 features. And while Google’s factory and OTA images are now available, there is little reason to manually flash the update unless you’re already comfortable with that process.
The next release worth watching is the stable Android 17 QPR1 update and accompanying Pixel Feature Drop, which should bring the more visible changes missing from these smaller September builds.
