Starting in August, installing APKs from unverified developers will require a new procedure called Advanced Flow. It involves enabling developer mode, rebooting the device, and waiting 24 hours with biometric verification.
After that, you choose: allow the APK installation for 7 days or indefinitely. The procedure is a one-time process and applies to all versions of Android.
Will the 24-hour wait stop you from installing APKs outside the store?
If it’s like existing hurdles, once, like enabling developer mode. I don’t think updates or subsequent apps will require more hoops.
I don’t think so either, but at the current level off stupidity all around, I would like to have something at face value
