Google has released the third beta of Android 17 QPR2, build number CP41.260731.005.A2, for testing on Pixel devices including the Pixel 6a, Pixel 7 series, Pixel Fold, and Pixel Tablet. Key features include enhanced theming options with an expanded color selection tool, an app lock feature accessible by long-pressing an app icon, and customization options for quick settings allowing users to rearrange elements. The lock screen has improved blur effects, and security enhancements include new restrictions on programmatic call forwarding and a confirmation dialog for manually entered codes. The beta also addresses several bugs, including display errors and device restarts. The update is available for Pixel 6 to Pixel 10 Pro XL models, and users can enroll in the Android Beta Program for installation. A subsequent update is expected in September.
