My friend uses a pretty hardened (as per him; I didn't indulge him when he wanted to give me the gory details) Graphene setup on his few years old Pixel.

Bank apps - as per him none work. Uber (no Lyft here; other taxi apps) work flawless. Payment apps, he said is a coin toss. On his phone even WhatsApp doesn't work. He anyway prefers Signal (which prob. nobody else uses in his circle except maybe me who has it installed on a secondary phone) or plain SMS. Basically most of the "normal" apps that add integrity checks don't work but he is fine with that.

Re: the bank apps: that really depends on the bank and the country. I live in a eu-west country and there are afaik no apps that do not run on Graphene (which did suprise me I must admit).

Whatsapp can work if you use sandboxed Google Play (I still use a Google account, I just don't want gplay to have effectively root on my device).

Depending on the level of integrity check your app might just work. Gory details: https://grapheneos.org/articles/attestation-compatibility-gu...

And like others said: no contactless payment, but I dont use that personally anyway.
