@arubislander For sure! There is no foolproof solution when running applications that are sensitive to device security outside of their intended environment, especially not in an emulated environment! (Having alternative operating systems and/or backup phones ready to go is always a plus)

@O.o. I can't confirm whether the Nordea app and BankID work on the Fairphone 4, but I can confirm that both work on the Fairphone 5 running Ubuntu Touch with Waydroid (as of today, anyway)! Hopefully, that means they would also work on the FP4.
