I don't know if there are more similar topics, but for beginners, now I'm showing the image-based process of using BPIP extension on mobile.
It's nice to use BPIP on mobile, but my suggestion is to use separate Kiwi browser with extensions only for bitcointalk forum, because adding extensions on mobile browser is reducing security a lot.
For everything else you can use open source Bromite browser that is one of the best options for Android, or Brave mobile browser as alternative.
Another option is Firefox and Tor mobile app, but they are much less secure on mobile than on desktop.
