4. Change fonts without root using a third-party launcher

How to change fonts on Android with root
1. Step #1
Once there, navigate to system > fonts > click the little icon that looks like a checklist on top and then click the triple dot menu icon on the bottom right and use Select All. Then copy the fonts somewhere safe. It's best to have a backup on your PC, too, just in case.
Keep in mind that you're going to be messing up with system settings, so you never can be too careful. If you're feeling this is out of league, then don't proceed.
2. Step #2
Once downloaded and installed, fire up HiFont. You'll be immediately met with a scrollable list with previews of many fonts. Pick one, click it, tap Download, okay the prompt, and then click Use on the bottom left. After the pack is installed, you'll be asked to reboot for the changes to take effect. Do it. Check out a few examples in the next slides.
P.S.: You can use HiFont in conjunction with a Samsung app without root. Do the same thing -- you'll only need to activate the font through Samsung's standard fonts menu, as illustrated in the previous slideshow.
