De1984 is a powerful Firewall and Package Manager for Android devices with multiple backend support for maximum flexibility and performance.

新版本 2.7.7
- Fixed: fast VPN firewall off/on could leave it off.
- Fixed: with Block All on root/Shizuku, apps could stay unblocked while the firewall showed on. Starts that can't read the app list now report the firewall down.
- Fixed: package actions could wrongly report missing root or Shizuku.
- Fixed: VPN mode drained the battery (CPU-busy tunnel, frequent root checks).
- Fixed: for work/clone profile apps, VPN rules, Force stop, Reinstall and new-app notifications could hit your personal profile.
