What are the differences between the custom firmware (2.0.9 for this instance purpose), and the official one?
I am asking also because I found bugs and issues within the official 2.0.9 firmware (such as occasional crashes of the launcher, video pauses, and bluetooth speaker not receiving audio after being paired) and would like to know if switching to the custom firmware (or downgrading to Android 5.1.1) will help resolve those.
Thanks!
