Free VPN Grass Auto-Connect on Android Startup
Auto-connecting a VPN on Android startup ensures your device is protected the moment it boots. This guide explains how to configure Free VPN Grass to start automatically, covers necessary Android permissions, and includes troubleshooting tips for common OEM restrictions.
How do I set up Free VPN Grass to auto-connect on Android startup?
There are two main layers to auto-connect: the app-level feature and Android system settings. First, enable the start-on-boot / auto-connect option inside Free VPN Grass. Second, allow the app to run in the background, opt out of battery optimization, and optionally enable Android’s Always-on VPN to enforce the connection at boot.
Checklist before you start:
- Install latest Free VPN Grass from Google Play
- Know your Android version and OEM (Samsung, Xiaomi, OnePlus, etc.)—some require extra steps
- Have device unlocked and basic familiarity with Settings app
Enable auto-connect in Free VPN Grass (step-by-step)
Open the app and sign in
1. Open Free VPN Grass and complete any first-time setup prompts. Ensure the app has been granted basic VPN setup permission when prompted.
Find Auto-Connect / Start-on-Boot
2. Go to Settings (in-app) → Connection or Auto-Connect. Toggle the option labeled “Auto-Connect”, “Start on boot”, or similar to ON. This tells the app to attempt connection at device startup.
Choose connection trigger
3. If the app offers triggers (Wi‑Fi only, Untrusted networks, Always), select “Always” or “On startup” to ensure connection at boot.
Save and exit
4. Save settings and reboot your device to confirm Free VPN Grass starts and connects automatically.
Grant Android permissions & handle battery optimization
Android restricts background activity for apps to save battery. To let Free VPN Grass run at startup you must allow background activity and disable battery optimizations for the app.
Common permissions/settings to enable:
- Autostart / Start on boot (OEM setting)
- Background activity / Allow background usage
- Disable Battery Optimization for Free VPN Grass
- Allow the app to run in the background and lock in recent apps if your OEM supports it
Steps (numbered):
- Open Android Settings → Apps → Free VPN Grass → Battery. Select “Unrestricted” or “Allow background activity”.
- Settings → Apps → Special app access → Battery optimization → Choose “All apps” → Find Free VPN Grass → Don’t optimize.
- For Autostart: Settings → Permissions or Security → Autostart → Enable Free VPN Grass (common on Xiaomi, Huawei).
- Lock app in recent apps (swipe down or long-press app card) on some Samsung/OEMs to prevent killing on memory pressure.
OEM-specific tips:
- Samsung: Disable “Put app to sleep” and set background usage to unrestricted.
- Xiaomi/Redmi: Enable Autostart and disable battery saver for the app.
- OnePlus/Oppo: Allow background activity and set app to “No restrictions” in battery settings.
Enable Always-on VPN and Lockdown (optional for enforced protection)
Android’s Always-on VPN forces your device to use the VPN for all traffic and can block traffic if the VPN is down (Lockdown). Use this for the strongest automatic protection.
- Open Android Settings → Network & internet → VPN.
- Tap the gear icon next to the Free VPN Grass VPN entry (or the app name under VPN apps).
- Enable “Always-on VPN”.
- Optionally enable “Block connections without VPN” (Lockdown) to prevent unprotected traffic.
Notes:
- Always-on VPN is available on Android 7.0+; behavior varies slightly across OEMs.
- Lockdown prevents any network access if Free VPN Grass fails to connect—useful for privacy but may block important services if the VPN is unstable.
Test and troubleshoot auto-connect issues
After configuring both app and system settings, test the behavior and follow troubleshooting steps if Auto-Connect fails.
- Reboot device: Confirm Free VPN Grass launches and attempts to connect automatically after reboot.
- Check notifications: A persistent VPN notification usually indicates an active connection.
- Inspect app logs: Free VPN Grass may provide connection logs in Settings → Diagnostics.
- Disable conflicting apps: Some aggressive task killers or security apps can stop auto-start behavior—temporarily disable them to test.
- Reinstall: If behavior remains inconsistent, uninstall and reinstall Free VPN Grass, then reapply Auto-Connect settings.
Troubleshooting tips (bullet list):
- If the VPN connects only after opening the app, re-check battery optimization and Autostart permissions.
- If Always-on VPN prevents boot, disable Lockdown and test to isolate the cause.
- Check Play Protect or device admin alerts that may block VPN apps.
- Contact Free VPN Grass support with logs if problems persist.

Frequently Asked Questions
How do I enable Auto-Connect inside Free VPN Grass?
Open Free VPN Grass, go to Settings → Connection or Auto-Connect, then toggle “Auto-Connect” or “Start on boot.” Choose “Always” or “On startup” if available. Save settings and reboot to test automatic connection.
Why won’t Free VPN Grass start automatically after reboot?
Most failures are caused by battery optimizations or OEM autostart restrictions. Disable battery optimization for Free VPN Grass, enable Autostart in device settings, and allow background activity. Reboot to confirm changes.
Is Always-on VPN necessary for auto-connect?
Always-on VPN is not required but it enforces the VPN at the system level and can block all network traffic if VPN isn’t active. It provides stronger protection but may be more restrictive for some apps.
Will auto-connect drain my battery?
Running a VPN in the background uses additional CPU and network resources, which can slightly increase battery use. Properly configured, Free VPN Grass minimizes impact; disabling unnecessary features reduces battery usage.
What if my phone blocks autostart for Free VPN Grass?
Check OEM-specific settings: enable Autostart, remove the app from battery optimization, allow background activity, and whitelist it in any system task manager. If needed, consult device support or Free VPN Grass support for guidance.
Conclusion
Setting Free VPN Grass to auto-connect on Android startup combines an in-app auto-start option with key Android settings—background permissions, battery optimization exclusions, and optionally Always-on VPN—to keep your device protected from boot. Follow the steps above, test after a reboot, and use troubleshooting tips for OEM-specific quirks.
