I am using the Wikipedia Android app from F-Droid (r/2.7.50282-r-2019-05-24 (50282).
One thing I miss is that there is a switch to show images always or on demand, but I'd rather having the images always while on wifi but on demand when on mobile data.
I think this requires a new permission for checking the connection type.
It is the first time I use Phabricator. Sorry for errors.
