Cracked back glass on your Galaxy S20 Ultra is not just an eyesore. It can let dust and moisture into your phone and make wireless charging unreliable. The S20 Ultra has a massive camera bump that makes back glass replacement more delicate. At My Cell Repair in Santa Rosa, California, we replace Galaxy S20 Ultra back glass for $180. We carefully remove every piece of broken glass, clean the frame thoroughly, and install a new back panel with fresh adhesive. Your camera lenses and wireless charging coil will work perfectly afterward. We are a local Santa Rosa shop. Most back glass repairs are done the same day.
