Thanks, I have android 9 on rom lineage 16. in the accessibility I already have active the zoom button that appears in the navigation bar with a little man icon, in fact I put the rom because my lg g4 nougat did not have that zoom option. Regarding the macro priam with font scale, I saw that if I click on the button it sends me the fonts at the default size, so it seems that the font scale function only serves to reduce the size and then bring them back to those of 150% offered by the android settings. I tried to do the macro that you proposed, but it does not work, it does not open the zoom even if I restore the accessibility values of the phone. I was looking for an alternative to big-font to use with macrodroid, just at the level of fonts across the entire operating system, as you proposed at the beginning also. It seems that there is also the text_size parameter in the app files. I enclose the macro about the zoom that doesn't work. I wonder if it would be possible to act in this way by implementing the display size instead of the font.
