Software Updates
Other than problems which you might normally equate with OS bugs on your desktop (e.g. every time you press the camera button, the to-do list comes up instead), software problems are usually best identified by inconsistencies.
Sometimes inconsistent can mean the screen says one thing but performance indicates another. Examples: the phone shows no signal strength but calls can be made just fine, the battery indicator swings wildly or shows no movement until the battery is practically empty. Other times inconsistency is in the behavior, such as when the speaker volume is fine except for one particular function. The Siemens S65 suffered just this issue when it was launched last year. The speaker was excellent, however the in-call alert (for call waiting or received messages) was exceedingly loud, no matter what volume the speaker was set to. A software update reduced the volume to a normal level.
The source of performance bugs are not as easily determined. Sometimes they are hardware related, sometimes they are software related, and other times they are hardware related but can be corrected or compensated for with a software update. Battery life is one such mystery, there have been times when battery life has been improved with a software update, other times users are doomed to recharge often for as long as they own the phone. There are other similar issues, such as menu performance (the speed at which the phone responds to button presses), poor reception or even sound quality. As unlikely as the last two seem, there have been occasions when each could be improved with a software update.
