Supposedly, this update fixed the voicemail but that was a trecherous lie. http://www.androidpolice.com/2013/12...ned-to-kot49e/
Two options at this point in time:
1) Get Cyanogenmod 11 M2 (or nightlies), this will allow you to swipe dismiss the notification. Another option is to take out the /system/app/phone.apk from the CM11 M2 ROM and put it in your stock ROM to get the swipe dismiss.
2) Hold down the VM notification and goto App Info and force close. (dont need to delete data nedjo67)
It will stay at 2 messages at any time. It basically is broken. You can use google voice to get REAL notifications that actually work but it will still show the broken voice mail notification.
Hopefully this will be fixed soon. I complained about this a while ago but Sprint does not think its a priority? Best place to get Sprint to fix it is to go on twitter and tell @sprint
care about your problem. Also make sure you tell @sprint
care that you are on the newest update or they will recommend you upgrade (not an actually solution for us, duh). The more people to harass @sprint
care, the better.
