Android 17 QPR2 Beta 7.1 Fixes Severe UI Stuttering on Pixel Phones

This update fixes multi-second freezes caused by page-reclaim thrashing for affected Pixels, available only to enrolled beta testers.

Overview

Google has begun rolling out Android 17 QPR2 Beta 7.1 to enrolled Pixel testers with compatible devices, generally Pixel 6a and newer.
The single documented change in the build fixes severe UI stuttering and multi-second freezes that occur under heavy memory pressure from page-reclaim thrashing and major page faults.
Users who experienced the freezes should see the problem resolved after installing the beta, but distribution is limited to the Android Beta Program or manual flashing of system images.
A device-specific regression has been reported for the Pixel 11 Pro Fold where Face Unlock may stop working until the user re-enrolls their face.
This release continues Google’s recent strategy of small, targeted QPR betas that prioritize stability and rely on tester feedback to validate fixes before any broader public update.
