In case you're receiving this message, usually after reinstalling Hello Neighbor, please try the following while the game is still installed:
- Update everything on your phone (including Google apps)
- Go to Settings > Apps > Apps > find Hello Neighbor and press on it
- Press Force Stop
- While still on the Hello Neighbor App info, press on Storage > Clear data
- Go back & Uninstall the game
- As an additional step, you could also check your system files for any HN leftover files and delete those too
- Restart your phone and install the game
- Run it
If it still doesn't work, don't hesitate to contact our support, and they'll take it from there. Please remember to share as much information about your case as possible (e.g., your device model, troubleshooting steps you've tried, screenshots, etc.).
