I've unrooted, done a factory wipe several times and each time my install for the 4.4.2 OTA update fails at 28%. When I press the menu button to see the reason why I get the following error (sorry for potato quality). It says that the AT&T Smart Wi-Fi apk has unexpected contents, but I don't even have that app and I never uninstalled it either. When I go to the Play Store I can download it and it still isn't a system app. As I said, I've done several factory wipes and I was hoping that would fix it since I hate doing wipes. Any ideas?
