TL;DR
- Google is adding an additional layer of security when installing an APK or updating an app through an APK.
- A PIN or biometric authentication will now be required in certain cases.
- This will be the case for APKs that Google thinks are malicious or didn’t come from the Play Store.
The push that non-Android and iOS phones need are apps.
And decent hardware, working out of the box and plenty of other thing I assume…
