Overview
What this part is
The Samsung Galaxy A20e has its fingerprint sensor on the back of the phone. The sensor button connects to the main board with a short flex cable. A crack, deep scratch or liquid damage can stop it reading your finger, and a torn flex stops it working at all.
After fitting, delete your old fingerprints and register them again in Settings. Choose the colour that matches your back cover. Your PIN, pattern or password still unlocks the phone during the repair.

Professional installation
How a technician fits this part
- Power the phone off and remove the SIM tray.
- Warm the back cover edges gently and lift it off with a plastic pick.
- Remove the screws and inner cover, then disconnect the battery before anything else.
- Unplug the fingerprint flex, then free the old sensor from the back cover or frame.
- Fit the new sensor in the same position, reconnect the flex and the battery, then register a fingerprint to test before closing.
- Refit the inner cover and screws, then refit the back cover with fresh adhesive.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
