If you go to Phone - ... - Settings - Call settings - SUBS settings - Mailbox, you can't use the back button in the blue bar at the top. The back button on the bottom works indeed.
I can confirm this behaviour.
Possibly a language related bug?
The option is called Voicemail in the English language, and the bottom back button works fine
I can also confirm it. My language is German, too.Just changed the language to English (US) and it still doesn't work.
It's not a question if the bottom back button works, but if the top back button works.And it isn't working on English (United Kingdom).
Ah! I retract my previous statement
My mind jumbled top and bottom as I was reading.
In which case, I also confirm this behaviour
I wonder if this is a Fairphone 2-related bug or if this also occurs on other devices.
I don't even have "SUBS Settings", or will it just appear if I enter a SIM card?
PS: Yes that's it. With a SIM I have the menu and I can confirm the bug too. I added it to the list.
