As indicated in an earlier post, my Motorola Razr Maxx has been disconnecting, since their software update. This update is through Google and is called Kitkat, no comment on that choice. This update, I believe is also for some Samsung phones as well.

After several calls to both Verizon and Motorola, which resulted in a net zero solution, I turned to the web. I found that there were several people having this exact problem, which is resolved by disabling the Wi-Fi when your in the car.

If you are having this issue, give it a try.

 

I have had the same problem intermittently with my Samsung Galaxy S4 since the upgrade. My solution is to reboot the phone. Then the problem goes away for a minimum of several days up to a week or two.
