Question: I noticed messages were not being sent from the Gmail app. I checked to make sure auto sync is enabled and it is. Any ideas? Beside the message it just says sending. I have other email accounts used by the Gmail app (e.g. yahoo) and they work fine. Also I can send and receive find from Outlook on my computer. I don't know what else information to give so feel free to ask for more. I'm using Xperia Z2 with Android 4.4

Answer: 
From the phone app, tap the Action Overflow button (...) in the top-right corner, then tap Call History. Tap any entry, then Details, and it will show you the date, time, and LENGTH of call, or calls (individually, in a list) if multiple were grouped together.
In the 'Recent Calls' list or 'Recents', touch the name of the person/business. NOT the picture or letter icon/initial, which will open the contact - or the phone icon, which will call them again.

If you touch the Name itself, it should drop down another menu with "Video call", "Message" AND "History". Touch History and you'll have a list of calls made WITH Duration.
