FWIW, I submitted an EU DMA complaint (Art 27 report) against Alphabet for unfair gatekeeping against third-party distributions like GrapheneOS via Play Integrity. More info: https://github.com/AlexAltea/blog/blob/master/posts/2026-06-...

Convincing developers, especially bank and gov apps, is near impossible and won't scale well. Going after Alphabet for not meeting DMA obligations seems the easier path. Might not go anywhere but worth a shot.

Graphene OS user here. Almost all of the apps I tried work fine. All the banking apps I use work. Have you tried reaching out to the app developer or the service and explaining what Graphene OS is and asking them to support it? I was able to persuade one app to do it.

Correction: i did get bank access. I just couldnt log into the bank without a google or apple controlled device.

lol, this problem stopped me from installing GrapheneOS early. But now.. I removed banking apps by myself because my state require room them to collect phone fingerprint and access to location EACH time they opened. So... looks like now nothing stops me
