Changing language in Android device on-the fly is needed when we are running or executing automation script in various languages.

To achieve language change of Android device, we have two ways:


You can watch a Youtube video OR follow the step by step procedure below

 Below command can be run from command line , to change the language of device.

   

adb shell "setprop persist.sys.language fr; setprop persist.sys.country CA; 

setprop ctl.restart zygote"

** But this procedure is having one issue, your phone should be ROOTED to make adb command into effect.  

2> Using ADB Change Language APP installed on your device (link)
