Thanks for telling us about this issue, Jackie.
We totally get how important it is to have a reliable phone that gives the best performance possible, and we're sorry the iPhone Air isn't working as expected.
If your screen is freezing:
-Start with a force restart by quickly pressing and releasing Volume Up, then Volume Down, then hold the Side button until the Apple logo appears.
-Update your phone to the latest iOS version available.
-Check your storage. Sometimes phones freeze when storage is nearly full.
-Identify problematic apps. If freezes happen while using a specific app, try reinstalling or updating that app.
-Reset settings: Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This won’t delete your data but resets system preferences.
