True Tone Iphone 14

Hi mudit272,

Thanks for posting here in Apple Support Communities. What happens when you use True Tone? Does the brightness not adjust on your screen? Check out: Adjust the brightness and color temperature on your iPhone, iPad, or iPod touch - Apple Support

Let us know, so we know how to help.

Thanks.

Thanks for the additional information mudit272. From here, we'd recommend making sure your device is updated, as a recent version of iOS 16 is available: Update iOS on iPhone - Apple Support

Do you see the different colored screen on every screen, or only when using certain applications?

Let us know, and we'll go from there.

Regards.
