This is so frustrating to developers.
Let’s say you do not want to change this, Samsung. Then, if anything, please add a way to detect if Samsung Dark mode gets applied. Preferably in CSS, for instance by adding a dataset to the html element. Or by adding some variable on the document or window object. (I’m just spitballing).
We simply need to be able to detect the Samsung Internet dark mode, so we can toggle certain elements to make things readable again.
