An AM screen on the Galaxy S20 Ultra is another name for its beautiful Dynamic AMOLED 2X display. If yours has lines, dead pixels, or touch issues, you need a professional repair. At My Cell Repair in Santa Rosa, California, we replace Galaxy S20 Ultra AM screens with high quality display assemblies for $200. We do not use cheap parts. We carefully remove the broken screen, install a new AM display, and calibrate the touch response including the 120Hz refresh rate. Most screen repairs are finished the same day. Come see us in Santa Rosa, and your S20 Ultra will look brilliant again.
