Install Adfree
No need to tick any selection . Just click "Download & Install Hosts". But you must install Universal Androot or any root apps to get this to work.
Click "Go Root" and make sure you are rooted before installing Adfree. Once the hosts files is updated, you should restart your phone to clear DNS caches. You will now have an "almost" ads free android phone (some ads could make its way back to your phone but keeping Adfree updated should solve the problem)
P/S : Rooting your phone will void your warranty. Use at your own risk.
