Is it just me, or is the game unable to auto-pause in the newer versions?
autopausing on sight never worked, but all the other options should. Do check the game options.
Oh but it did! I played the game with auto-pause on sight for a very long time on my android phone. That is, enemy sighted. The game options are set in the ini-file (nothing changed since it worked).
it can't work now, that much we know (in bg2, bg1 is a bit different). If it did before, it was by coincidence / errors in other parts. But the android version is very old, so it's hard to tell. I bet at least three of the autopause options don't work there. The options gui is also unreliable in that version, so you are correct to configure via the ini file.
So yeah, wait for a fix, but it is a pretty complicated matter in this case.
on-sight autopause was fixed to work everywhere already.
