I think using a smartphone for banking is very dangerous: - banks often use phone (for example, SMS) as a second factor for authentication, for example to confirm transactions. Compromising a phone thereforer provides full access to your account. Some banks even allow to perform payments by sending SMS without logging in. - many phones do not receive security updates in time. And those updates close only public vulnerabilities. - while Android has good permission system, many apps have a very wide set of permissions, including permission to read or send SMS messages, or permission to use accessibility functions, so compromising such an app can also be enough.
