• Fixes Display scale has not had its settings in the settings section of the main menu on Android for several versions  #95037
• Removes the languages option: it was previously disabled but its label was still visible in the quick settings dialog

@akien-mga @Calinou I added this to the 4.3 milestone but this can also be moved to 4.4 as the issue is not critical.
Based on the task description, it seems to be a regression however.
