What you need

  1. Samsung Galaxy A53 5G Fingerprint Sensor Replacement, Heat the back cover: step 1, image 1 of 1
    • Prepare an iOpener and apply it to the back cover for at least two minutes to loosen the adhesive underneath.

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