I tested about a bunch of browsers on my Samsung phone (including Chrome, Firefox, Maxthon, Dolphin, Cheetah, Brave, Puffin, Opera, and Yandex), and eventually decided that the "Samsung Internet Browser Beta" was the best of them for me: https://play.google.com/store/apps/details?id=com.sec.androi...

My main demands were a browser that had a reliable "reader mode", a black background "night mode", allowed reasonable ad blocking, and had a full screen mode with minimal clutter. The Samsung browser isn't perfect, still occasionally makes me mad, but definitely is worth trying if aren't fully satisfied with what you are using.
