A couple of weeks back when I rebooted my phone I ran into a strange problem on my Samsung phones.
An annoying voicemail notification which I’m not able to remove.
A rough googling ended in understanding that this is a common issue which much people are facing. We the people who keep on clearing notification bar now and then would find this really annoying. Soon after the swipe to erase didn’t work I clicked on it, tried fixing the voicemail number, all the way searches for a setting to fix this out. Hard luck there weren’t any. You are here most probably because the same thing is eating your head.
Here’s a quick fix for the same.
