Google Details Android’s New Sideloading ‘Advanced Flow’ With 24-Hour Wait, Rolling Out in August

Google says the high-friction process is meant to deter social‑engineering attacks.

Overview

  • The one-time setup lives in Developer options and requires a coaching check, a device restart with reauthentication, and a mandatory 24-hour delay before users can allow installs from unverified developers for 7 days or indefinitely, with persistent warnings; installs via ADB are unaffected.
  • The advanced flow becomes available in August 2026 ahead of broader policy changes, delivered through Android components so it reaches current devices.
  • Google will begin enforcing developer identity verification for broad distribution in September in Brazil, Indonesia, Singapore and Thailand, with a wider global rollout planned for 2027.
  • Developers distributing outside Google Play must verify identity, upload signing keys and pay a $25 fee, while free limited distribution accounts let students and hobbyists share apps with up to 20 users without ID or a fee.
  • Developer and digital-rights groups continue to object that mandatory verification raises privacy concerns and barriers to entry, even as Google cites higher malware risk from installs outside Play.
