[Magisk] belidzs:
I can confirm the Raiffeisen banking app probably fails because of something else. There is no Xposed on my system, both safetyNet checks pass, Magisk Manager is also hidden. I have tried to activate MagiskHide to Phone-related apks as well since the app requests call management permissions, but it didn't help. I've also chmodded /proc/net/unix to 000. I tried disabling USB debugging and developer mode altogether.

What's interesting is that I think the app looks for the native camera app on my Mi A1 which was not present initially, but then I've created a Magisk module which placed the original camera apk at the correct location which did not help either. Decompiling the source revealed that it uses Vasco's technology for authentication which is also used by com.EquitasDigipass and interestingly enough it looks like it tries to do something with its resources too.
