my up button for volume does not work and need to turn incoming call volume up. is there an app to do this

Hey skeith75,

Thanks for the question. Based on the information you have provided, your iPhone may need to be serviced to fix that button. However, if in the meantime you would like a workaround for turning the volume up on a phone call, you can use Assistive Touch:
