Are you manually checking for the update?
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
I just received an update and we are still on 4.4.2 So I am very upset. I have Serious TXTing issues which are documented to be a 4.4.2 problem. With the recent update not going to 4.4.4 I don't see it in the future at all.
I am ready to switch to a new provider
Probably won't be a 4.4.4. Lollipop 4.5 will be out in Nov. Maybe they are waiting for it.
Android Lollipop is 5.0
5.0 will be out for Google Nexus devices in November.
How long to do you think Samsung will take to test, install, and layer on their extra software.
Then it goes to Verizon for testing, adding in more software that you can't uninstall.
If you see this before summer 2015 it will be a minor miracle.
I have read Samsung will release 4.4.4 for the S4 to Verizon sometime in November. Verizon will have to test it on their network before it is released to it's customers. How much time that takes is anyone's guess.
