I have an issue with my BB 9300. When typing (texting) a small box appears in the top right corner of the screen possibly with an arrow or an x- can't tell because it's too small for me to see. While that box is present my BB delays (freezes) while I'm typing. I have the latest OS installed. I have tried pulling the battery, reinstalling the OS and pulling the card. Also, a white screen appears on occation.
I have removed all apps that I have downloaded. I have dropped the phone once getting out of my car but that was a year ago so I don't think that would affect my BB now. It has never gone for a swim.
