On both my old 520 and now my new 830, I get pop-up messages which are essentially useless! (These are both personal text messages and device-generated messages.) They are dark gray on a black background. For me, they are impossible to read. Worse, they cover several data fields, so I have to clear the message I can't read.
Is there a way to change the text color to white-on-black, black on white or yellow, etc? I have been putting up with this annoyance for a couple of years now, and I was hoping the 830 would let me change this. Apparently, NOPE!
