Hi.
I’m running a local language at my phone. This makes sense for many of my apps, since they are developed for a local audience. But: For more specific apps (like f-droid), which are not local-dependant, I always run the app in English, because translations are often not correct enough to search for errors, solve miscellaneous tasks etc. But f-droid automatically choses my local language, and hence make is difficult for me to use (my terminology in respekt of development, geek-stuff etc. are simply English and not local).
