Blocking ads system-wide on an Android device isn’t that difficult. And it works without rooting your phone. Just follow the steps below and you will set it up in less than five minutes:

1. Download any DNS Changer app from the PlayStore like mine I provided here.
2. Start the app.
3. Add a new DNS server with following IP addresses provided by adguard.com:
   94.140.14.14
   94.140.15.15
4. Click connect.
5. Open apps or websites containing ads and see how good it works

If it does not work instantly try deleting any cache, where the ads may be served from.

Surfing without ads is more secure and saves you a lot of your bandwidth.

Main features:

• Set a custom DNS server or select one from the list
• Works on all connection types like mobile, WiFi, ethernet etc.
• “Connect on boot” feature
• Pause & continue DNS settings without opening the app
• Pin security (for e.g. parental control)
• No root needed

How does it work?
Lilly uses Androids VPN service feature to set a DNS server for all types of connections. There is no routing made through our server, which you can verify with a speed test and checking your IP. You can also check your systems connection settings technically.
