How can i change language in German on android?
Sorry for my reply. I am only an F-Secure user (their home solutions).
I think that by default F-Secure Android application should use system's default language (as most of other applications?!) if it is supported one.
Maybe it is possible to overwrite by certain installation flow (for example, from My F-Secure portal with certain parameters). But sounds that there is no option to set up it via installed application.
Does your experience is about FS Protection (F-Secure SAFE beta for Android)?
If so - maybe good to create kind of report/feature-request under beta-portal.
If your experience is about stable solution - maybe possible to ask clarification by support request (chat as example): https://www.f-secure.com/en/web/home_global/contact-support
By the way - do you want to change language because it is your language (but is not chosen as device language)? Or your application with unexpected language after installation?
first thing: what's your gsm operating language ?
