Some time recently my active display started acting differently. The phone now flashes once and then shows the email envelope icon briefly when I get a new email. It never had the flash before and I find it distracting. This happens with all three email apps I use, so it doesn't seem to be related to the email app itself. I cannot find any way to turn this off. Does anyone have insight on this, is it happening to others, and does anyone know how to turn off the flashing?
