YOUR ANDROID DEVICE NEEDS TO HAVE ROOT ACCESS FOR THIS TO WORK!
This video is an updated version on how to install zawgyi font on android 6.0.1. The device in this video is Samsung Galaxy S6 running android 6.0.1 (Marshmallow). Most people couldn’t use the previous method so I hope this will work for you 🙂 I cannot guarantee that this method will work on every device. Recently Note 5 and s7 owners say it doesn’t work.
