I rooted my phone to change my native font,but font installer root & similar apps failed to change the device font. any suggestions would be great.
The first thread '[INDEX][REF][GUIDE][RESOURCE] Welcome to your Motorola Moto G - Resource Guide (post #4 end)' in MOTO G General, there's a link for flashing multiple fonts through CWM recovery! It's safe and remember backing up the data to stay so. I have iOS 7 helvetica font running on my rooted MOTO G!
I rooted my Moto G to take full benefit of having full access to my device as I need it. More specifically, I did it to use Xposed modules like App Setting and the graphic card spoofer app GLTools. These are not necessary of course, but I feel like having custom DPI on an app to app basis should be a normal Android feature everyone should have access to without root.
