Dismiss button not responding

Greetings Symone100,

Thanks for reaching out in Apple Support Communities. First, we'd like to provide you with a few steps that can assist you with getting your daughters iPhone to respond:

"On your iPhone 7 or iPhone 7 Plus

1. Press and hold both the side button and the volume down button until you see the Apple logo.

2. If your phone doesn't turn on, follow these steps to check your hardware and charge your phone. You might need to charge for up to an hour."

More details here: If your iPhone won't turn on or is frozen

Once the iPhone powers on, the following information can assist you with the alert that appears on the device:

"Here's when these alerts might appear:

• Your accessory is defective, damaged, or not Apple-certified.

• The accessory isn't supported by your device.

• Your iOS device has a dirty or damaged connector.

Try these steps to fix the issue:

Update to the latest version of iOS

Some accessories might require the latest version of iOS. Make sure that you update to the latest version of iOS.

The latest software version that is available for an iPhone 7 is iOS 15.7.2

Make sure the accessory is compatible

If this is the first time that you tried to use the accessory, make sure that it works with your device. Some accessories only work with certain models of iPhone, iPad, or iPod touch. If you aren’t sure, contact the manufacturer.

Check the connections

Disconnect and reconnect the accessory to see if the alert goes away. If it continues to appear, check the connectors on the accessory and your device for damage or debris. If necessary, gently remove the debris and clean the connectors on your device."
