I know I can change the system font with several root apps, but this method is sketchy and was responsible for bricking one of my phones in the past. The SmartWorld fonts are installed as an APK if I'm not mistaken. My knowledge of how APKs are structured is fairly limited, but I was wondering if it would be possible to decompile one of the font APKs (if necessary. Again, not incredibly familiar with them), change the font file to a custom one, and install it on the G3 in a way that it would act like any other SmartWorld installed font and can be selected from the Settings > Display > Font type menu.
TL;DR is it possible to install a custom, non-SmartWorld font as if it were from SmartWorld and use it with the stock font changing settings? Thanks in advance.
