Got the KitKat update about a month ago on my Droid Razr Maxx HD. Since that time, I've been regularly losing text messages. I'll see the notification come in at the top of the screen (I even know who sent it if I'm using the device when it comes in), and the Messaging app (default app--that's all I've ever used for texting) shows the number of unread texts. But sometimes when I click on either the notification or the Messaging app, the text message isn't there. I have reset the app to default settings, and sometimes this will make the message appear--but usually not. If I shut down and restart the phone, I lose the message for good and the app goes back to showing no unread texts. This seems to happen most often when someone with an iPhone sends a group text message. Prior to KitKat, I never had a problem with group messages or missing texts. Any idea how I can fix this? I have one waiting for me on my phone now that I can't get.
