I have translated these lines because they are in the general file in English (insted of "strings_not_translatable.xml"). These labels are very common in Spanish. Actually, they are the common labels in the smartphones: Galería as Gallery, Tomar foto as Take a picture... With this strings I tried to make it more "integrated" with the phone.

Anyway, I just try to help in the translation using my experience as geocacher and my native language. But just do what you think is better :)
