Expected behavior

They have given a feature to change the language on their app into few languages. But when I change language on this app. After restarting the app again I expect the language of this app will be still remaining as my selected language.

Actual behavior

When I changed the language the pages of Facebook has been changed as my selected language. But when I restart app the page of Facebook has been changed to English.
Suppose I selected Arabic from the list. After restarting the app the page of Facebook changed into English but in settings, it shows that Arabic is still the current language of this app.

How to reproduce

• Download and install v3.8.1 of the app from here on your android device.
• Open and go to Settings.
• Then tap on "Change app language" option.
• Select a language.
• Get back to the main page. Make sure the page of Facebook changed as your chosen language.
• Close the app. Make sure the app is not running in the background.
• Reopen and see the Facebook language has changed to English. Then go to Settings and see your selected language is still there.
• App version: 3.8.1
• Operating system: Android 6.0.1
• Device: Galaxy A5 (2016)
