I had the strangest thing happen, and came up with no answers through search, so I thought id post it here. Since I have a really weak signal, I'm constantly trying *228 and hoping for a miracle. Normally when I dial *228 the screen is simply grey in color. Yesterday though, the top of the screen was red at the top. Tried again and back to grey, so I just assumed I was seeing stuff. Today, same thing, but this time screen was blue at the top. Was able to re create this twice, and now back to grey. I know it has nothing to do with the option you're going for, because this happens before I select a number. Just curious if anyone else has seen this, and what the colors might mean.
