GrapheneOS Isn’t Happy With Google Over Pixel’s Widening Head Start

Google's September 2026 Pixel Update Bulletin includes patches that affect standard Android platform code, relevant to both Pixel and non-Pixel devices, which have not been included in the regular monthly Android Security Bulletin. GrapheneOS has noted that Android 17 QPR1 introduced new developer APIs not present in the Android Open Source Project (AOSP) for the first time since Android Honeycomb, with one new package and modifications to sixteen others. GrapheneOS is backporting Pixel firmware and drivers from QPR1 onto Android 17 but lacks permissions to distribute this work. Additionally, there has been a delay in Google’s compliance with a GPL source request, with access granted over two weeks after the initial request. Starting in 2027, Google will require all Android app developers to register with them and provide legal identification and signing key evidence, complicating the process of sideloading unverified apps. GrapheneOS and other organizations are advocating for the Keep Android Open campaign against these developments, which may restrict competition and tighten Google's control over the Android ecosystem.

Android apps can now check security patches down to individual device components

The new AndroidX Security State libraries, with stable releases of Security State v1.1.0 and Security State Provider v1.0.0, allow developers to evaluate the security status of individual device components. They provide three levels of security patch information: Device Security Patch Level (DSPL), Published Security Patch Level (PSPL), and Available Security Patch Level (ASPL). These libraries enable checks on critical components of the Android operating system, including system modules and the Linux kernel, which are represented by version numbers rather than monthly patch dates. Applications that prioritize security can utilize this detailed patch information to assess vulnerabilities, particularly those tracked as Common Vulnerabilities and Exposures (CVEs). The libraries also integrate with the Open Source Vulnerabilities (OSV) database for access to Android Security Bulletin data and device-specific vulnerability reports. Additionally, Android 17 allows manufacturers to declare individual security fixes beyond the stated security patch level, and Google is working with manufacturers to transition their OTA update clients to this new standardized system.
