I only use my browser adblocker on my mobile phone but if you wish to use Ublock origin on your mobile phone then you should use KIWI browser as it allows you to install extensions on your mobile phone.
I used it back then to run bpip.org extension and it was cool although I haven’t tried any other extensions but you could try and see if it really works.
Is this not this browser:
Any app I see contains ads, I can not use it. You can see contain ads there. I use Tor and Duckduckgo.
The first explanation is chrome which I do not like to use and it is still talking about the in-app ads blocker.
When I have time, I will look into these, but your first link makes me think the other way. I will find time to look into both.
