I am starting a series of articles about localization (l10n) and UX-writing with real-life examples. I'll take an app or a website and show you where it could be better in terms of writing. I'll start with Facebook for Android (version 09-2019) and it's Russian locale. First, the good part. Generally speaking, the app has a very decent translation into Russian, considering the number of other supported languages (few dozens). Special thanks for the Language item in Settings: developers often force the app to use system language, but this is not always convenient. For example, the Russian Yandex.Maps persistently switch me to it's localized English version because of my phone's system settings, but it's not very useful when you're Russian in Russia. Most of the time, Facebook app works nice with endings of nouns (1 комментарий, 8 комментариев). Alas, there are things in the app that could be just somewhat better.
