VPN keeps turning off?
It's not an app issue. Your phone's system closes VPN in the background.
Why is this happening and how to fix it?
What's happening
Android closes background apps to save battery — even ones that barely use any. Tuman VPN gets caught in the same net.
What to do
Add Tuman VPN to battery exceptions. It won't affect battery life — VPN already uses minimum power.

Screenshots may look different on your version of the system.
Steps
1
Turn off battery optimization
Open: Settings → Apps → tap the gear → Special Access → Battery Optimization → Tuman VPN → Don't optimize
This removes the system's automatic power-saving limits on the app.

2
Lock in recent apps
Go to: Recent apps → long-press Tuman VPN → tap the lock icon
Locked apps stay in memory and won't be cleared out.

3
Turn off deep optimization
Open: Settings → Battery → Battery optimization → three dots → Advanced optimization → turn off both "Deep optimization" and "Sleep standby optimization"
These aggressive modes force-sleep the VPN in the background.

Heads up
OnePlus sometimes resets these settings after a system update. If VPN starts dropping again, check them after the next update.
Always-on VPN
For maximum stability, also enable Always-on VPN — it keeps the connection live even if the app briefly restarts.Settings → Network → VPN → Tuman VPN → Always-on VPN
