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.
