Q: Can i change my iPhone because the Touch ID lag

change it to what?

If you believe that your iPhone is defective, it is under warranty, and you have tried the basic troubleshooting in the manual, then you can make an appointment at the genius bar to have it evaluated.

Hi

It may help to follow the steps here, under "Get help with Touch ID":

• Use Touch ID on iPhone and iPad - Apple Support

If the issue persists, contact Apple Support (mail-in service may be available) or make a Genius Bar reservation with a view to having your iPhone checked and, if recommended by Apple, serviced (whether under warranty, if eligible, or via chargeable out-of-warranty service):
