It's funny imagining people saying this for anything but a phone. "You can only download from the Microsoft store or you should consider your device corrupted." Take caution, but you don't need to rely on daddy Google alone.
you need Google to tell you what safe and what's not? have you ever used a desktop operating system where you usually install programs from different sources?
Note that for this attack to work, you have to be on Android 11 or below (or possibly an earlier patch) as by default accessibility services aren't allowed to draw-over or interact with elements in the settings app unless you explicitly override it in developer options.
This extends to some other areas, like for when biometric/system lock APIs are used.
