The Notification bar in android provides notifications such as new missed call, new message and any notification generated by a system or installed apps. It is one of the good feature of android. We can simply clear these notifications by clicking on the corresponding notification or by clicking the clear button depends by the ROM you are using. Even though Notification is a good feature it feels annoying if we can't clear the notification and the the icon remains forever.
In some android devices Voicemail notification icon remains and we can't clear it by clicking on the notification or by the clear button. It may be because of the network provider issue or the Android ( I don't know the actual reason ).
