I already told you in a previous post about how to easily set the radio in English, without breaking your head.
Today I bring you the modified application «My PTT+». This application makes our life easier, by this I mean that not only allows us to put our radio in English without having to change the language of the phone, but also allows us to perform a «fine tune» or fine tuning. Install custom firmwares without problems.
The truth is that the application is «amazing».
You can visit the Github page here.
Enjoy it!
