W580i side button buggy

Seems strange. You can try reflashing your phone.

You can try loading the lastest firmware.

Well, the current firmware (R8BE001) still has some bugs in it (light issue still hasn't been fixed) but it does improve the speed of the menus and updates the installed version of Java. It probably wouldn't hurt to give it a try and see if that resolves your issue. (You can always revert back to R6BC002 if you wanted to)

If the issue is still there in R8 maybe it's hardware related?

what do you mean by power cycle

I believe he means just shutting off the phone removing the battery and putting it back together and turning the phone back on.
