I have a Droid Global 2 and ever since I got the update on my phone it has not been working right. At times I cannot hear people when I call them, but they can hear me and same goes for when they call me I cannot hear them. Then with text messages I cannot send them and I cannot receive them. And when I do receive them I get them hours later. To fix these problems for a short amount of time I have to take out the battery and then start up my phone again. But it doesn't last long. Also my phone will turn off and restart itself randomly when I am on the phone calling people when I am using it for other things. It has gotten to a point that I am about to get another one. I had this problem before and I got a new phone out of it, they said it would be fixed with the new phone but it was not. So if there is anything that I can do before I get another one please let me know.
I'm going thru the same issues as you, actually about to get on the phone with customer service, as I'm now on my 3rd Droid 2 since I originally purchased mine. Rebooting the phone will normally clear this up for a little while, instead of going thru all the trouble of reboot via battery pull.
