I've noticed that on my iPhone 6 plus, if it has been turned off and I have received texts during the time it was off, when I turn it back on and my messages pop up on my homescreen, it just says the phone numbers and not the names of the contacts. However, once I open the phone and go to view the messages in the messaging app the names are all there like normal. Is there a reason for this? I'm running 8.1.1, but I think I remember this happening even prior to updating to the latest software. Thanks!
