As soon as it tried to override my Home settings I uninstalled it. Even after telling it no, it still opens in a faux Home screen that may confuse users. People want to customize their mobile devices not have someone else customize it for them for one app. There are "launchers" for that. I didn't explore one feature, just removed it after the first launch. Edit: Leave the "OEM upgrading your device" to the device manufacturer and the user's service providers updating process.
