1.How to use SuperVPN?

Click connect button in the main screen to use SuperVPN. If Android/iOS system show a dialog to request a connection permission, click OK or Accept to continue.

2.How long can I use SuperVPN for each connection?

As long as you can. We don't set time or traffic limitation on each connection

3.Why can't I use internet after connection established?

Fist of all, check your network connection. Then make sure you've disabled battery optimization for SuperVPN in Android's battery setting (which means enable background activity for SuperVPN). If you enable Smart Proxy, you also need to make sure all the apps you need to proxy is checked in Smart Proxy setting.

4. How to disable battery optimization for SuperVPN?

In most Android devices, open Android's Setting-->Battery-->Battery optimization, select "All apps" in the dropdown menu, find SuperVPN and set it to "Don't optimize".

In HuaWei devices, open Android's Setting-->Battery-->Launch, find SuperVPN in the app list, switch off to "Manage manually", enable "Auto-launch" and "Run in background".
Or you can find battery setting in "Protected Apps".

In Samsung devices, open Android's Setting-->Battery-->App Power Saving-->Details, find SuperVPN in the app list and disabled it.

In other devices, you may find it in Setting-->Battery as "Background activity" or "Protected apps".

5.What is Smart Proxy

On Android 5.0 or above, you can only enable some of the apps to use SuperVPN to proxy traffic, and all the other apps use local network. For example, if Facebook and Skype are blocked in your country, make them checked in Smart Proxy. After the VPN connection is established, only Facebook and Skype's traffic will go through VPN, and all your other apps will perform as good as usual.

6. When I try to connect, Android system request a permission, but I can not accept it, why?

You may be running some app which changes the screen color or opens a floating window. Android's security system prevent VPN to be running under these cases. You need close this kind of app temporarily to continue.
