How to block all ads on your Android device without rooting

block ads on android

Back when the concept of what is today known as the “Internet” was envisioned, the focus was solely on the educational aspect of what the technology could do. Over the years, the online community has not only morphed the internet into a way of connecting to users across the world, but today stands as one of the most useful marketing tools, thanks to the inclusion of online advertisements.

From the websites you visit every day to the mobile apps that you use, ads are almost everywhere. While advertisements do help to keep these websites and app developers in the business, some of them can be so intrusive that they ruin the user experience. Several ad-blockers for Android have come and gone, but one that remains is the DNS66.
