Yes, you will get the non-genuine message to pop up when you first but the phone.as a banner. Eventually it will move into the settings as badge item but it will no longer show on the lock screen. For 2, I haven't actually tried that but I have heard of people messing with the date/time settings to expedite the message from showing. I can't confirm that either work as I haven't personally tried myself. We typically just tell customers upfront that the message is a control by the OEM which in no way affects the function of the device. Especially when they see the price different between OEM repair and aftermarket they don't seem to care as much.
