Notification bar looks different after AT&T update
There is a row of gray semi-circles across my notification bar ever since AT&T installed an update (without my permission... I was notified of the update and chose the option that said "Remind me later," but the next time I turned on the phone there was a msg. on the screen saying that it was updating right then and was unavailable until it finished). I'm sorry I can't remember exactly what the update was; it seems like it was maybe a firmware update... but I'm not sure. Here's a screen shot of how it looks now. It's difficult to see the icons on the notification bar. Can someone help me?
The update occurred approx. 2 weeks ago.
This is my first Android phone. I've had it since the beginning of June, and I still have trouble making sense of how it works and all the options... even what the settings mean, zuch as all the volume settings and why some change without my having opened the settings to change them.
