    • Prepare an iOpener and apply it to the back cover for at least three 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.

    • Secure a suction handle to the bottom edge of the back cover, as close to the edge as possible.

    • If the back cover is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.

    • Lift the back cover with the suction handle to create a small gap between the back cover and the frame.

    • If you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Insert an opening pick into the gap you created.

    • Slide the opening pick to the bottom left corner to slice the adhesive.

    • Leave the opening pick in place to prevent the adhesive from resealing.

I want to replace this component but I can't find the part. Is the ******NFC Antenna & Charging Coil part the same in the standard s21 and the s21+, or are they different sizes and incompatible?
