“Google is constantly optimizing and tweaking its apps through various A/B tests, and the latest one for the Play Store has us scratching our heads quite a bit. We’ve noticed that the familiar and handy install button is disappearing for some in the Play Store’s search results, which means that you actually have to tap through to the full app listing to install an app. This behavior isn’t in place for all results and apps, though, making the tweak feel arbitrary and random…”
Do apps really install the moment you press the button on Android? On iPhone you have to confirm through Face ID or by entering your passcode first.
Yes, in my experience.
Installation is just the same as getting an app on desktop and telling it that yes, you do want to run it. (I know that sometimes requires a password, but sometimes it doesn’t and I’m not sure why but that’s how Android Play Store installations work).
It depends on whether or not your account is setup to request authorization each time.
