Second bug - launch "Clock", select "New alarm", tap "Repeat", select any day(s), "Done". Short names of the days are now displayed in "New alarm" window at the "Repeat" button. They are displayed in wrong language, different then system one. My guess: it takes language from the "Regional settings" instead of "Device language" (in the "Regional settings" menu). Selecting "Never" and "Every day" for "Repeat" displays fine (in device language).
