How do I get rid of the badge on my settings app?

Based on that link it sends you to, you will see the following notification:

"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."

Evidently you are going to have to live with this notification on your screen for 4 days.

Did you have your iPhone repaired by a 3rd party?

Seems like the replaced screen is not compatible.

That is why you are getting that message, it is not an Apple display.

I don't believe you can turn off that one. You can check your display settings and turn off True Tone and all other such setting and see if it will go away.

This is what happens when you have the screen replaced on your phone by an unauthorized person with a part which is not authentic. What happens when you tap learn more?

Yes, in that fine print it said it would do that for 15 days.

Hope you saved a lot of money but realize you have voided the warranty on your iPhone.

Did you NOT read the read the rest of the statement? It said it will show as a badge for 15 days. Guess you'll just have to wait for the 15 days to pass.

Hope you don't have any issues.
