I work in an office that has no cell signal. So when I step into my office, my bars go away, I get the no signal symbol and then 30 seconds later my phone will alert me that I have a voicemail (when I don't have one). When I step into an area where I can get a signal, the voicemail notification goes away and my phone is fine. All of this started the day I updated to Android 4.3.
I've called Verizon multiple times and all they can do is tell me to reset my phone, which I have done multiple times.... I also have had my voicemail reset
It's really annoying since it will vibrate and the screen lights up as usual for 30 seconds.
Now my battery drains faster since my phone vibrates every 5 -15 minutes all day while I'm at work.
I too have this exact issue. The false VM notification is annoying for sure (it is always 2 "new" VM, when in fact there are zero), but the more annoying aspect is the "mobile network unavailable" message. Not only does it happen every time I move to the center of the building, but it tends to persist for a few minutes after moving back to areas that I know I have coverage.
This began with the 4.3 update, and nothing else has changed. It is so annoying, that I have spent hours searching for a resolution which is how I ended up here.
Sorry it has taken a while to respond. I *might* have solved my problem.
So right now my Verizon voicemail is disabled and I get the false voicemail alert when I lose signal. I do not receive any other messages.
Our wifi hubs have been updated, so now when I go into work, I get wifi all day long without interruption. Since then, no more false voicemail alerts!
Just to experiment, I disabled my wifi and sure enough I got the false voicemail notification. Turned wifi back on and it eventually cleared itself after a minute. Hope this helps!
