    I was wondering what was wrong with my phone, i thought a reboot would fix it and forget to do it everytime.

    The lags are actually quite unpleasant and noticable, i wonder how it wasn't caught before the release.

      Gosh, I have noticed a number of my apps (Pixel 11 fold 'pro') simply halting under high workload. This is that I suppose.

        The linked post seems to say that Pixel 11 hasn’t received QPR1 so far and might not have this bug?

        Pixel 11 series received a bug fix release near the start of September 2026 with the 2026-09-01 patch level. That update wasn't Android 17 QPR1 and also doesn't include the September 2026 Pixel firmware/driver security patches. Perhaps they noticed this issue and cancelled it.

        I had assumed this was just Google effectively "ending support" for my 9a by forcing some AI thing into my lowish RAM. I can't believe even the latest Pixel users are having this problem since I thought they actually QA those.

        Sorry but at this point, for me it is shame on every Googler for continuing at a company that has absolutely no interest in user experience anymore. It's on you, directly or indirectly.

          It was introduced on September 15th for Pixel 6 through Pixel 10a. It will potentially never get fixed for the Pixel 6 and Pixel 6 Pro on the stock OS due to those now being past their guaranteed update periods. For GrapheneOS, it's fixed in out latest release for the Pixel 6 through Pixel 10a now available in our Stable channel.

          Early in the month, the Pixel 11 series received a partial September 2026 security update release. Those didn't receive Android 17 QPR1 or the full 2026-09-05 Pixel security patch level on September 15th. Pixel 11 series users aren't on the latest major release of Android so they don't have the latest and greatest features. It's likely it was cancelled for the Pixel 11 series due to regressions but they still released it for the older generations of Pixels.

          We haven't launched Pixel 11 support yet due to the many issues with those. MTE support not being available at launch was the biggest issue but there are more. We'll see if they're usable devices meeting our security requirements with Android 17 QPR2 in December 2026.

            Thanks for the explanation! Wow releasing regressions only for older devices, that's something.

            GrapheneOS looks really good thanks for working on it. Unfortunately Google Pay is critical for me and it's unfortunate Google is gatekeeping that, but I will look on jealously.
