what phone(s) do you use and what's the default web browser on them?
mine Samsung Galaxy a32 4g (will probably switch to a Google pixel 7a somewhat soon) and the default web browser is Firefox but i am in the process of switching to iceraven
Firefox is the only mainstream browser that supports ublock origin on mobile in my experience. Although they've made some very weird decisions settings wise over the years. Like not letting you touch "hidden" settings anymore
