Absolutely. I generally use English (not my native language) as default language for my Android phone, but there are some apps where the English translation is pretty awful and that I prefer to use in the original language. For these use cases app developers needed to add in-app language switchers, which can be a bit of a pain to implement. There are still situations where the setting in Android won't cut it though, namely if Android doesn't know the language at all. For example, Android doesn't know Romansh (https://en.wikipedia.org/wiki/Rhaeto-Romance_languages https://en.wikipedia.org/wiki/Rhaeto-Romance_languages) is a thing, so if an app wants to add a translation for it, it needs to be an in-app switch.
