Very interesting. I don't own a cellphone so I'm on a computer with a 24" monitor and the new font is lighter than the old and harder to read. I'm not the only one with this problem from reading through this thread.
I tried dinking around with how my system displays on my monitor by checking out all the Contrast Themes but no help there. They all sucked.

Then I switched the System Display option by turning on Night Light (
use warmer colors to help block the light), thinking that might help. This is what turning that on did to my screen:

Needless to say, I immediately switched it back.

And! The silver lining here is... that orange in the image I posted isn't what the new WS theme is being changed to. lol Thank goodness for that. lol
