KIT KAT upgrade has decimated my Maxx HD's ability to reach out to a tower and to use WIFI, both of which were not a problem before this update....I live in an area where coverage is not the best, but has always been enough to get 2 bars of 4g...........now after this poorly executed update, i have little to no coverage and have trouble getting wifi to work more than a few feet away......OK verizon, What now?? This has made a great phone almost useless. Please respond
