Sub optimal character design in a font

[bugith]

Hi
I post here because I was swindeled signing-in at nothing.community : we just can't give feedback, start a new discussion or even reply to anything over there. Not even breakout. Just a honeycomb to catch customers @mail. Small initial nothing is the word.
I thought it was the place to give a feedback, forbidden, so I do it here.

In the Contacts app, the 0 (zero) character is far too similar to an uppercase "o" (O). Just compare here: 0O
