Block System-wide Ads without Root on Android

Android OS is the most used smartphone operating system which has captured more than 80% of the world smartphone market share. The popularity is immense because of the fact that there are a huge number of Android applications and games that gives the user to choose between different options. Moreover, there is a lot of flexibility in terms of app development and developers are coming up with new apps and games every now, which is amazing for Android users. Besides, almost all of the applications or games available on the Google Android Play Store are available for free.

However, but have you ever thought that how do these developers earn if they give the users app and games for free? Now, you might have come across various ads that pop-up either while playing games or while using any application. These ads are pushed by the developers in order to earn revenue and this is the reason why you get those apps and games for free. But, there are many times (almost every time) that these ads get a bit intrusive and annoying. These ads hamper the experience that the apps and games could provide the user. Moreover, previously it was possible to block these ads only if you have a rooted device.

But, in this post, we will show you how to block system-wide ads without root on Android. There are some apps that claim to accomplish this but, they drain out the battery. The name of the application that we are going to use is DNS66 which is developed by Julian Code. This app is pretty simple and it uses VPN to block ads on your Android device. So, without any further ado, let us get straight into the article itself;

What is DNS66?

DNS66 allows blocking hostnames via DNS. This can be used for ad blocking. It also allows other DNS servers to be added, for more privacy. Compared to AdBlock Plus, this works without proxy stuff; and it also does not require root, as AdAway does: DNS66 establishes a VPN interface and redirects DNS server traffic to it. The VPN interface filters the traffic, only allowing queries for hosts that are not blacklisted.

A host (list) can be configured as to allow, deny, or ignore. A later entry in the list overrides a previous entry. Custom DNS Servers can be configured as well, using the same UI, but no differentiation is made between ignored and denied servers.

However, there is a downside while using DNS66. It is that the app leaves a persistent notification in your notification tray. Moreover, you will just have to deal with it because currently there is no way to turn it off. Except for blocking notifications from the app altogether. But, this application does what we want it to do and as they say, you need to give something to get something.
