No matter the manufacturer, every Android phone has one thing in common: its software base. Manufacturers can heavily customize the look and feel of the Android OS they ship on their Android devices, but under the hood, the core system functionality is derived from the same open-source foundation: the Android Open Source Project. After over 16 years, Google is making big changes to how it develops the open source version of Android in an effort to streamline its development.
Banking apps just buy into false security peddled by google. They are absolutely not necessary for security of an app, just like kernel level DRM & anti cheat is not necessary for video games.
Yeah, they’re the same situation of anti cheats, and banking apps might be even more conservative on these decisions vs. game developers
