Here's a copy/paste, sans hyperlinks:
Developer verification will be enforced on certified devices with Google Play Services installed, which is the majority of Android devices. There are options to bypass the restriction:
- Use a free, uncensored Android system like /e/os, LineageOS, or GrapheneOS that does not preinstall Google Play Services.
- "Degoogle" by removing Google Play Services. If it is a system app, you can uninstall it using ADB.
- Install apps via ADB. Google has already confirmed that ADB will continue to work in the future. You can either use ADB from a PC as described below or use a wireless ADB based installer like anyapk.
