One of the only big downsides I've noticed with GrapheneOS is that several banking apps don't work with it at all thanks to being tied to Google's verification ecosystem.
Luckily I have hardware 2FA keys from my bank so I can authenticate using that. It also slightly decreases the suck-factor from whenever the phone decides to fly off down a drain. This may not be the case for you, so do your research on what you need for daily living.
I contacted my bank, insisting that GrapheneOS is one of the most secure OS on the market and therefore should be supported if they actually care about users' security (it's actually far more secure than all the old, far less secure but Google-approved devices out there). They acknowledged an fixed their app, one of the most popular in France.
Still missing Android Pay but that's due to Android Pay being closed. I wish banks would do something and support NFC payment systems that don't require the device to be controlled by Google (how can we be okay with this?!)

What about the small matter of having to purchase a Google phone in the first place?
Yup, also Google Pay doesn't work, though there are other providers which work fine (Curve Pay I think works in all of EU), but it just made me carry my wallet everywhere and I understood I don't mind that at all.
Author is installing Google Play Services it seems, wouldn't that work around this?
In any case, for me this also sort of defeats the purpose: I'd rather break free from Google and Apple, not just (stock) Android and iOS.
Does anyone know if HSBC's UK app works on it? I've seen inconsistent reports that it does and doesn't.
Edit: ignore this - there's a list elsewhere in this thread!
Of course that is highly depdendet on the bank used, but so far none of my banking apps didn't work!
If you are using a rather popular banking app, chances are high that it has been discussed in the GrapheneOS forum.
Anyway, with google play services installed, mine have worked out of the box.
yep - tried GrapheneOS for the first time today and my banking app detected that the phone was jailbroken.
