This is truly ironical that some apps refuse to work on system that is much secure.

I use LineageOS and it is true that I have to use Magisk to have banking app working. And I understand that this is not for everyone.

I just wanted to mention that there is a way to use older phone and have security updates longer than vendor provides it. And even longer than Apple.

I get the argument about binary blob updates. Security is never 100%. And it also shows another reason why binary blobs make things worse.
