Screen flickering in gmail with iPhone 12 Pro Max

Hello and welcome to Apple Support Communities, sushil122!

We understand you're seeing flickering within the Gmail app on your iPhone. We'd be happy to provide information to help you address this.

The screen recording you posted does not show any flickering. It's possible that it's an issue with the display itself and not the app. To test this, you'll want to restore to factory settings and the iPhone up as new. Make sure you have a back up:

How to back up your iPhone, iPad, and iPod touch

Restore your iPhone, iPad, or iPod to factory settings

If the issue does not happen with a new set up, restore the back up: Restore your iPhone, iPad, or iPod touch from a backup

Check to see if the issue continues there and let us know the result.

Have a great day!

sushil122,

If this only happens within the Gmail app, you'll want to reach out to them for assistance with their app:
