Play Integrity

Google Play Integrity is used by banking apps, Google Wallet, RCS messaging, and certain other apps to verify that your device hasn't been tampered with.

Integrity levels are categorized into three tiers:

• MEETS_BASIC_INTEGRITY: Passes basic software checks.
• MEETS_DEVICE_INTEGRITY: Passes device certification checks (required for Google Wallet and most apps).
• MEETS_STRONG_INTEGRITY: Passes hardware-backed key attestation checks (required for very very strict banking and government apps).

How to Import a Keybox on spes

1. Enable Developer Options:

   • Open Settings → About phone.
   • Scroll to the bottom and tap Build number 7 times until you see "You are now a developer!".

2. Import the Keybox XML:

   • Go to Settings → System → Developer options.
   • Scroll down to the Apps section.
   • Tap Configure keybox XML and select the downloaded keybox.xml file from your storage.
   

You Can Disable Developer Options Afterwards

Once you have imported your keybox.xml, you can safely turn off Developer options using the toggle at the top of the menu. The imported keybox will continue to work in the background, and disabling Developer options helps when certain banking apps detect developer mode!
