There are only problems with a bunch of applications that recently decided to use Play Integrity API not with every banking app nor Netflix.

This is the list: https://grapheneos.org/articles/attestation-compatibility-guide#apps-banning-grapheneos

In fact those applications should not work with Lineage unless Play Integrity API is patched/cracked someway in Lineage.

In this case, thanks to regulation, it seems GrapheneOS team is talking with European Commission about this problem with Play Integrity API https://fosstodon.org/@GrapheneOS@grapheneos.social/113623767380032309 and the only hope is a movement of the regulator against this policy of Google.

It runs in Lineage? Lineage is certified by Google Play Integrity API (I doubt it)? or Lineage tricks Google Play Integrity API?

If you install GrapheneOS, you do not need root, so GrapheneOS is in control of the phone not the user. The key here is if GrapheneOS is secure enough to be certified by Google Play Integrity API. is it security or other issue? perhaps Google is not supporter of FOSS ROMs, perhaps it is not fun of how GrapheneOS removes permissions to Google Apps, …

If it is not security, this is a kind of monopoly to control which ROMs are allowed to run apps.

the problem here is not the banks or apps, the problem is Google Play Integrity API, which is supposed to enforce to run apps in secured phones and it is used to ban secured ROMs such as GrapheneOS and it allows to run apps on outdated phones without security patches.

I don’t know what I was thinking on to type it 😅
