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.
