I have Motorola W385 cell phone. All of my minutes and text minutes are current and paid. When I flip open the cell phone now the "Contact" icon shows a phone handle and is red. It has not been like this in the past. Sometimes is stays just a steady red with the handle of a phone, and sometimes it alternates from that icon to another icon that is not red and looks like a notebook page.

I have Straight Talk, bill is paid, never late, and I have minutes left, text left and data left.
What is making this contact icon red? Is someone hacking my cell phone? I have had it for about three years and never seen it like this before. All suggestions welcome or ideas, please help. I don't know what to do or how to get it to stop being red. Thank you for any help -
