Email flips while reading

Hey there Midwing73,

Thanks for visiting the Apple Support Communities.

If you're using the native Mail app, there are up and down arrows in the upper right of the message. If you tap one of these arrows, it will take you to the next email in your inbox. This is expected behavior.

If these arrows are not being tapped (either intentionally or inadvertently), we can recommend taking the following steps:

1. Close the Mail app: Close an app on your iPhone or iPod touch - Apple Support
2. Restart your iPhone: Restart your iPhone - Apple Support
3. Make sure you have the latest iOS version installed on your device: Update your iPhone or iPad - Apple Support

Don't hesitate to respond back if you still need help.

Have a wonderful day.
