Yeah works fine for me. Although only two banks in my country apparently throw a fit over non stock phones. The fit being biometrics not working. So YMMV. I’d say it’d worth a try. Revolut also works for me so if you’d want you can link your bank with that and use it.

Just flash GrapheneOS!

I can highly recommend GrapheneOS!

You could use aurorastore. Sdmaid is useless IMHO. I don’t see the point in it. I used to be rooted but now using GrapheneOS I am not anymore and although I miss customising the navbar pill and notification bar height it is safer this way.
