In my OnePlus 3T phone I have a system-wide font which is annoying. How can I change it?

[AC Question]

On many apps I have a font on which all letters are with double lines. It is very annoying. It is like a "=" instead of a "-" for all characters.
How can I change it ?

Welcome to the forums! I am not familiar with the OnePlus 3T - can you change your font by going into your Settings app (look under "Display" for starters)? Often, various themes or launchers you can download from the Play Store will have customizable fonts.
