What is the Notification?

Genuine Screen or Battery?

If it is telling you that you do not have a genuine display or battery, then take this back to the person(s) who replaced it, and have them place a genuine one in there.

You will see a notification on your Lock screen for the first 4 days that you use your device and in the Settings app for 15 days. After that period, you can find the notification by going to Settings > General > About.

You’re stuck with it for about 15 days. 😞
