I know a while back that the current setup OS: Android (Mobile) Browser: Dolphin (stable/beta tamper) it was having issues removing scripts. Believe in some cases it's just needed shim support for some of the buttons.
Not sure if this got fixed though within recent times, I barely test on mobile but this was observed about 6 months ago.
(I'll add this here to not open another topic)
help pls :c
