Not sure if anyone else has noticed this too, but in the calendar, the week starts on a Sunday and can't be changed. I tried changing it to Monday through "settings --> apps --> calendar" but it stays stuck at Sunday. In PR1.1, I could change it from Sunday to Monday, but after every restart it would revert back to Sunday and I'd have to change it again. Other than that PR1.2 seems to be working fine (OTA update, 16GB/Black/Indonesian).
