Google Rolls Out Advanced Sideloading Process with One-Day Waiting Period

Google is gradually rolling out its 'advanced' sideloading flow for Android devices ahead of developer verification. The new process, designed to increase friction and protect users, includes a one-time, one-day waiting period between enabling the install of apps from unverified developers and actually installing the app.

The advanced flow requires users to go into Developer options and turn on 'Allow apps from unverified developers.' After that point, warnings will appear before the user can start the 24-hour waiting period. The setting can be turned on temporarily (for seven days) or indefinitely.

Google confirmed in June that its developer verification changes are on track to launch in September in select regions. The 'Android Developer Verifier' app announced in March is what delivers this functionality, but it is rolling out gradually.

Developer verification starts on September 30 in Brazil, Indonesia, Singapore, and Thailand, but will go global next year. ADB installs are not affected by the new process, and developer options can be turned off after enabling the advanced flow.
