Use this guide to replace a damaged back cover on your Samsung Galaxy A52.

If you do not replace the adhesive seals when reassembling, your device will function normally, but will most likely lose its water protection.

You’ll need replacement adhesive to reattach components when reassembling the device.

  1. Samsung Galaxy A52 Back Cover 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 Back Cover Replacement, Insert an opening pick: 手順 2、 2の画像 1 Samsung Galaxy A52 Back Cover 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 Back Cover Replacement, Slice the adhesive: 手順 3、 2の画像 1 Samsung Galaxy A52 Back Cover Replacement, Slice the adhesive: 手順 3、 2の画像 2

    • 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.

終わりに

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 you install it.

To reassemble your device, follow these instructions in reverse order.

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