はじめに

Use this guide to replace the loudspeaker on your Samsung Galaxy A52.

You’ll need replacement adhesive to reattach components when reassembling the device. If you do not replace the adhesive seals when reassembling, your device will function normally, but will most likely lose its water protection.

  1. Samsung Galaxy A52 Loudspeaker Replacement, Heat the back cover: 手順 1、 1の画像 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.

  2. Samsung Galaxy A52 Loudspeaker Replacement, Insert an opening pick: 手順 2、 2の画像 1 Samsung Galaxy A52 Loudspeaker Replacement, Insert an opening pick: 手順 2、 2の画像 2
    • Secure a suction handle to the right edge of the back cover, as close to the edge as possible.

    • If the back cover is damaged, 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.

    • In case 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.

  3. Samsung Galaxy A52 Loudspeaker Replacement, Slice the adhesive: 手順 3、 2の画像 1 Samsung Galaxy A52 Loudspeaker Replacement, Slice the adhesive: 手順 3、 2の画像 2
    • Slide the opening pick to the top right corner to slice the adhesive.

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

    • Insert a third opening pick at the bottom edge of your phone.

    • Slide the opening pick along the bottom edge of your phone to slice the adhesive.

    • Leave the opening pick in the bottom left corner to prevent the adhesive from resealing.

    • Remove the back cover.

    • Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

    • Secure the new back cover with pre-cut adhesive or double-sided adhesive tape. After installing the back cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

  9. Samsung Galaxy A52 Loudspeaker Replacement, Unscrew the motherboard cover: 手順 9、 1の画像 1
    • Use a Phillips screwdriver to remove the ten 4.4 mm-long screws securing the motherboard cover.

終わりに

If possible, turn on your device and test your repair before installing new adhesive and resealing.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.

Repair didn’t go as planned? Try some basic troubleshooting, or ask our Answers community for help.

Excellent and very detailed tutorial thank you! Do you know what the impedance of the loudspeaker should normally be? After changing the charging port and reassembling my phone the loudspeaker is not working anymore. Many thanks in advance. Emmanuel
