Geeks Have Landed: There are many benefits to rooting your Android. Root provides access to parts of the phone that were otherwise unavailable, meaning that you can increase the speed of the phone and even install the operating system from another device. The main reason I use root, is to customize my phone to have it exactly the way I want. One of the ways of doing this, is by changing the system’s font.
By changing the font on your Android, you change the entire font. Not just on the home screen, but the text throughout the entire operating system. This is why it requires root access.
