Afaik there is an android compatibility layer but I don't know if it allows banking apps to works
Maybe I'm out of the loop but what is everyone doing with banking apps on their phones that's so essential. I see this argument all the time but it's baffling to me.
It would not in principle, those rely on hardware backed keys with Google's latest iteration of Google Play Integrity. The only success people have had is by using leaked vendor keys and spoofing device fingerprints for old A11-era devices which did not have the hardware baked in. In time even this avenue will no longer work. People have been trying to get around it for a while [1] but afaik the concept is cryptographically airtight.
