My phone was working well before the upgrade, now the battery is draining quickly even when its not in use, its overheating and I can't send or receive pictures via text. I have done a soft reset, I have gone and changed the settings so its not using so much battery..but Nada. I haven't done a hard reset because I would rather not because it would take me forever to re-load everything onto my phone. I tried to calling the 800 number but was on hold for 30 minutes. I am getting frustrated with this phone..is it possible to uninstall KitKat?
