I have a Nexus 4. For the calendar, you have to scroll to enter a time, which is inconvenient for events starting at :30 (30 minutes past the hour). On the same phone, for the alarm clock, you manually enter the time using a keypad-type display. Is there anyway to use the keypad-type display rather than scrolling for the calendar function?
When creating the event click on the time that you need to change:
Then when the set time pop-up comes up press on the number instead of scrolling.
