Have you ever heard of adguard?. Its the app that we are going to use in blocking those advert in your android apps etc.
How does it work?
Adguard uses local VPN technology to filter traffic without you rooting your device . After running the app, it immediately starts to filter all your Internet bandwidth quietly and quickly.
Steps to use adguard to disable advert!
First download the adguard app here install and launch it.
Go to Advance settings >Filtering method and select high-speed.
Go down to filtering mode , I recommend you choose local HTTP proxy, but if you are not rooted choose Local VPN. (Reason why you should choose Local HTTP proxy because you can't use a VPN together with Adguard if you choose Local VPN)
Go to general settings and tick Adguard Autostart ( what this does is , it makes sure that Adguard is always running when you reboot your device)
