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.
Oh well… interesting to see how this slides further down. Might be the push Linux phones need. I think my current phone will be the last android I will have
