I rooted my Xperia SP and managed to change all fonts to Roboto Condensed.
Only issue I am having is with the clock widget. I am not sure which font is used by the stock clock widget.
I managed to change the time font of the clock widget to Roboto Condensed.
I changed Time font by replacing
.SST-UltraLight.ttf with Roboto Condensed font.
But can't change the font of Date and Alarm information. It uses some other font.
Can anybody help me on this?
