blokada VS tracker-control-android

You can read about Blokada here https://blokada.org/ and their v6 will also be in your App/Playstore but as said is subscription only. Lucky Android users can keep scrolling down until you see v5 offered which is completely free (not in Playstore btw). Unfortunately v5 isn't available for iOS. It works though, you won't see another, just a blackout timer that runs for 35 seconds (which does also mean you wait 35 seconds for the few ads that only runs for 15 seconds).

But it's due to game? Or is it Vivo thing? Can you try with https://blokada.org (blocking ads system-wide trough DNS)?

here try this https://blokada.org/

If you use the Firefox browser with the uBlock Origins extension, it blocks almost every ad. I use the Samsung Internet browser with Blokada 5 and it's a nearly ad-free experience.

blokada.org

For those on Android, download Blokada 5. It's a free open-source systemwide adblocker app. Don't download Blokada 6 on the Play Store. It's a subscription cloud-based app. Google doesn't allow VPN-based adblocker apps in the Play Store. If you have a Samsung phone, Blokada 5 is in the Galaxy Store.

with [0] you can disable network access by application.

Iam looking for a firewall app on android and there are many options like NetGuard, TrackerControl, InviZible Pro and Karma Firewall.

Tracker Control.

TrackerControl: FOSS. Has global and per-app block settings. https://trackercontrol.org/

Assuming you're using an Android phone, either you switch to NewPipe or download TrackerControl. Both remove YouTube ads.
