I noticed the other day that every once and awhile, the side buttons on my W580i go buggy on me. Usually when in standby mode, pressing the side buttons turns on the back light so that you can see the current time, missed calls, etc. Sometimes though, pressing them does nothing in standby. I have to restart phone in order to get them to work properly.

Anyone else notice this? It's not that big of a deal, just annoying
