Use this guide to remove or replace the screen on your Samsung Galaxy Note20 Ultra.

The fingerprint sensor is embedded in this phone’s screen. If your fingerprint sensor isn’t working, you will likely need to replace the entire screen.

There is a significant chance that you may break the unreinforced and fragile display panel during this procedure. If you’re trying to reuse the screen, be sure to apply plenty of heat and be extremely careful during the prying stage.

For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

  1. Completely power off your phone before you begin disassembly.
    • Completely power off your phone before you begin disassembly.

    • Heat an iOpener and apply it to the left side of the rear cover for one minute.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the screen and internal battery are susceptible to heat damage.

  2. Apply a suction cup to the heated edge of the rear cover, as close to the edge as possible. If your back glass is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken panel. Pull up on the suction cup with strong, steady force to create a gap between the rear cover and the frame.
