I have an issue with the update. The option in call features on JB said Power BUTTON Ends Call. In KK it is supposed to say Power KEY Ends Call. I noticed that no matter if I toggled that option on or off that the power button ends the call. I called VZW who 3-way called LG. LG said it was VZW responsibility since VZW signed off on the update. LG wants to charge shipping to and from repair while VZW wants to send a replacement. This is after diagnostics and resets have already been done. One rep's supervisor has the LG with the same problem. Several others did not have the issue, or were unaware to it as of yet. If enough problems were reported of the same nature, LG would issue an update to fix bugs, but would still have to go through testing and then to VZW for testing, and that might be quite some time if at all. I am holding off on returning it, hoping something fixes itself. Otherwise I might still be stuck in a loop of return, replace, update, errors, repeat.
