Introduction

What you need

Step 1

              Remove the SIM tray

Insert a SIM card eject tool, SIM eject bit, or a straightened paperclip into the hole on the SIM tray, located at the top edge of the phone next to the plastic antenna band.
If you inserted the tool into the other hole, don’t worry—the microphone and the ingress seal are mounted out of harm’s way.
Press firmly to eject the tray.
Remove the SIM card tray.
When reinserting the SIM card, ensure that it is in the proper orientation relative to the tray.

Step 2

              Heat the back cover

Unplug and power off your phone before you begin.
Heat an iOpener and apply it to the back cover’s right edge for two minutes.
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.
As you wait, take a look at the image of the removed back cover and take note of where the adhesive is located.

As you wait, take a look at the image of the removed back cover and take note of where the adhesive is located.

Step 3

              Create an opening gap

Rest the heated right edge of the phone on something that is about 0.5 inches (13 mm) thick. This angles the phone for the opening tool.
Brace the left edge of the phone with your fingers so that the phone won’t slide. Pull on the suction cup with firm pressure.
Press the edge of an opening tool into the seam between the back cover and the frame.
With the opening tool in place in the seam, slide it back and forth along the seam to loosen the back cover.

Step 4

              Insert an opening pick

Heat an iOpener and apply it to the same edge of the phone for two minutes.
Apply a suction cup to the back of the phone, as close to the center of the right edge as possible (where the adhesive is narrowest).
Pull on the suction cup with strong, steady force to create a gap between the back cover and the frame.
Insert the point of an opening pick into the gap.
Due to tight tolerances, this may take multiple attempts.
If you are having trouble creating a gap, your best bet is to apply more heat to the edge and try the previous step again.
You can try applying a few drops of high concentration (over 90%) isopropyl alcohol into the seam to help loosen the adhesive.
Do not apply excessive force with the pick, or you will risk cracking the back cover glass.

Step 5

              Slice through the adhesive

Slide the opening pick along the edge of the phone, slicing through the adhesive.
Do not attempt to slice the adhesive holding the corners down before applying heat. If you do, you may crack the back cover.
Leave a pick in the seam to prevent the adhesive from re-sealing.

Step 6

Apply a heated iOpener to the bottom edge of the phone for two minutes.
Insert an opening pick into the right edge near the bottom right corner.

When cutting around corners, be sure that the corner is thoroughly heated.

Step 8

Once you have sliced around the phone, twist an opening pick in one of the edges to help separate the back cover from the frame.
Lift the back cover slowly. Use opening picks to slice any remaining adhesive.
Remove the back cover.
During reassembly, this is a good point to power on your phone and test all functions before you seal the back cover in place. Be sure to power your phone back down completely before you continue working.
Follow this guide to reinstall the back cover, transfer and install the camera bezel, and replace the adhesive.
If desired, you may reinstall the back cover without replacing the adhesive. Remove any large chunks of adhesive that might prevent the back cover from sitting down flush. After installation, heat the back cover and apply pressure to secure it.

To reinstall the top midframe:
Align the midframe’s top edge to the phone and lay the frame down on the phone.
Use fingers to apply pressure along the midframe perimeter to snap the midframe clips back into place. The edges should sit flush against the phone edge.

Dominique - Jun 12, 2019

Hallo ich hab seit kurzem ein galaxy s10 und habe versehentlich statt dem eigentlichen Sim-slot in das untere Mikrofon neben den Lautsprechern “gestochen”. Ist dort direkt das Mikrofon dahinter oder ist dieses seitlich von dem Loch angebracht?

Arthur Shi - Jun 12, 2019

Hi Dominique,

The microphone hole is angled. You did not damage your microphone.

Zorro1 - Oct 1, 2019

I have the same problem, with the S10 open, I mixed up the microphone slot and the SIM card, I definitely did not damage the microphone?

Arthur Shi - Oct 1, 2019

Correct. You cannot damage the microphone by pressing anything into the hole. For more details, see here.
