We need Linux on phones. Bank apps not needed as long as I can use browser. But do need some things like wireless cards, popular apps like Sonos and Spotify working.
Unfortunately these days bank apps are required by the banks for "security", and good luck getting anything done without the bank app installed on your phone.
The only other alternative available is SMS but that is being phased out (rightly so) for being insecure.
Unfortunately many banks in the UK no longer offer a web portal or physical branches.
I'd love to see legislation that mandated a functioning web experience for critical services like this (banking, utilities, etc) - otherwise it will continue to further entrench the current duopoly.
(I suppose this is also an instance where I should do a better job of voting with my feet and supporting services that do offer this)
