I can understand. Ads are super annoying. I am using TUTUApp's Ad Blocker which is available to download for free - https://appvn.me/tutuapp/ Install Adblock/AdGuard Pro via TUTUApp for free and you will get rid of them.
use "Adguard" apps. This is most reliable ads blocker for your phone. It filters different ads from your screen. It is very useful and i get good result from this. I used many adblocker apps. Most of them are useless. But this is quite helpful for blocking ads
The VPN service I use blocks ads, but I don't always want to run my devices through a VPN, especially when I am at home. I used to root all of my Android devices but I am past that now--it's not worth the bother. Chrome supposedly is going to start blocking ads in the future, but I don't know if that carries over to the mobile version or not, and to what extent. Since I have so much synced in Chrome, changing to another browser isn't going to happen. Don't want that clutter on my phone either. I keep only what I need on each phone and tablet, and dump the rest.
Someone who can block ads without needing root would get a ton of downloads. Sadly it's difficult to make happen.
