Ok, let’s see if I can help; )
To 1: banking apps are a pain. Some are working out of the box, some will need my hack with Magisk and some won’t never work. I fear for the verification the goolag services are needed. It’s like inbuilt qr code verification, it’s also not working because of missing goolag services.
To 2: fingerprint is not implemented, because of missing hardware driver. I do have 3 Xiaomi devices with pie or q and nowhere fingerprint is working. I think.it’s because of copyrights
To 3 and rest:
Bliss launcher needs a lot if enhancemets. I don’t use it. I’n using TotalLauncher from Aurora. It has such a lot features, yoy can’t use then all
