Frequently Asked Questions
This is usually a Play Integrity issue. GrapheneOS includes Sandboxed Google Play which satisfies most Play Integrity checks, but some apps additionally check for hardware attestation. The fix is to go to Settings → Apps → find the banking app → enable Exploit Protection Compatibility Mode. This resolves the issue for the vast majority of banking apps. If your specific app still doesn't work, the GrapheneOS community forum at discuss.grapheneos.org maintains a list of app-specific workarounds.
Your device comes with Sandboxed Google Play available as an optional install — just go to the Apps section in Settings to enable it. This lets you use the full Google Play Store normally. Alternatively, F-Droid is an open-source app store with thousands of privacy-respecting apps, and Obtainium lets you install apps directly from their GitHub releases. All three approaches are covered in the setup guide that ships with your device.
Yes. GrapheneOS delivers over-the-air (OTA) updates automatically, just like stock Android. Updates incorporate Google's monthly security patches, often on the same day or faster. Your device will prompt you when an update is available. For Pixel 9 series devices, you have 7 years of guaranteed updates from the original release date. We recommend keeping auto-updates enabled in Settings → System → System Update.
Yes — and we encourage you to do so. Install the Auditor app from the GrapheneOS App Store (pre-installed on your device). Open it and run an attestation. It will confirm via hardware (Titan M2 chip) that: verified boot is locked, the OS is the official GrapheneOS build, and the device has not been tampered with. You can also have a trusted contact with another GrapheneOS device perform a remote attestation for additional assurance.
The Duress PIN is a separate unlock code that, when entered at the lock screen, triggers an immediate and irreversible full device wipe — including all user profiles and encrypted data. To set it up: go to Settings → Security → Screen lock → set your normal PIN → then find the Duress Password option. Choose a PIN or password you would never enter accidentally. Yes, it is truly irreversible — once triggered, the encryption keys are destroyed and the data cannot be recovered. This is by design.
