A quick heads-up on the Calendar app that comes loaded on the Z1s.....it is NOT the Google Calendar app. I was checking my calendar tonight and noticed none of my appointments were being displayed. Did the easy thing by refreshing my calendar and still no appointments! Went to Google Play, downloaded Google Calendar and all is well. Pretty strange. This is where Google splitting out the apps from the OS could be confusing to some people. The two apps looked very similar but they are not the same. If you look at the icon for the calendar app that comes loaded on the device you will notice that the page with the date is flat, If you look at Google's Calendar app icon you will notice that the page with the date is creased in the lower right-hand corner. Is this true for the regular Z1 and the Z? Shame on Sony for this situation.
