Right now to me your attitude seems shocking. The man above was kind enough to take time out of his day to help you, I don't understand why I should be helping someone who doesn't appreciate what people are trying to help you with.
I will as a matter of fact, help you, however, since I'm not Android this may end up being a bit difficult.
This is one way of changing it:
a) change the DNS servers of a VPN connection
When using this way, the DNS servers you enter only get used while the VPN connection you set it for is active.
- Open "Settings", then navigate to "More..." -> "VPN".
- When connecting via PPTP or L2TP from your Android device, you should have at least 1 connection listed here.
If not, see our article Android for instructions on how to create them. - Tap and hold your VPN connection, then select "Edit profile".
- Check "Show advanced options" - more options will appear.
- Here, enter your DNS servers separated with a space at "DNS servers (e.g. 8.8.8.8)"
- For example, you could enter here "8.8.8.8 8.8.4.4" or just "8.8.8.8".
- Hit "Save".
- When now connecting with this VPN profile, your Android device will use the DNS servers you entered.
This is another way of doing it:
b) change the default DNS servers
When using this way, the DNS servers you enter only get used while no VPN connection is active.
To be able to change the default DNS servers your device is using, you might need root (if "Set DNS" fails without root)
The easiest way to do this is to use e.g. the app "Set DNS" from
https://play.google.com/store/apps/d...ytechie.setDNS
The other way to do this is to manually edit the file /etc/resolv.conf after removing its write protection.
This can be done either with a terminal app like Android Terminal Emulator (via vi or other command-line based text editors),
or you can use your favorite text editor, as long as it can access the root folder /etc
