LG wants to protect your new G3 from unauthorized factory resets with its new partnership with McAfee. The G3 will come pre-installed with a version of McAfee Mobile Security that will give you a kill switch for the smartphone. This feature will let you disable the phone remotely in case you lose the device or it gets stolen. Some of the features available through the McAfee app include an antivirus, data backup, remote tracking, and remote lock and wipe. The lock screen of the app can block factory resets and any rooting attempts of your device. The app will be free for G3 users for five years.
