incoming texts stopped being DISPLAYED last month...
I've had a similar problem just a couple of weeks ago.
My incoming texts suddenly no longer are being displayed automatically for me to read.
I AM STILL getting the texts, but I now have to open up the text app to see "IF" I have any new texts.
Before, whenever a new text came in (even when my phone was "asleep"), it would automatically open up and the actual text message itself would be displayed for me to read.
I went into the Text settings, and checked the box for notifications in the status bar, which only put the alert of a text in the status bar, but still does NOT AUTOMATICALLY DISPLAY THE INCOMING TEXT.
