Samsung Galaxy S4: How to Use VPN in Android 5.0.1 Lollipop

In Samsung Galaxy S4, you're allowed to add VPNs (Virtual Private Networks) and connect to one of them. You'll have some benefits when using VPN, e.g: you can access your business or home network over Internet with more securely anywhere you are, you can have private browsing even when you're in the public network, you can access country-blocked websites by connecting to a VPN located in another country, etc.

How to add a new VPN profile?
Before connecting to a VPN, you have to add the VPN profile first in your phone. You can do so by using the following steps:

1. While your phone is unlocked, swipe down the top of the screen to open up the notification panel and then tap at the top right to go to the settings menu.
2. Tap Connections tab.
3. Tap More networks.
4. Tap VPN. As a note, if you turn off your lock screen or use swipe as your unlock method, you'll be asked to use another secure screen lock type, e.g: PIN, password or pattern. You just need to follow the on-screen instructions to complete the lock screen configuration.
5. Tap at the top right to add a new VPN profile.
6. Enter the desired name for your VPN profile in the Name field.
