Introduction

This guide is written for the genuine Samsung screen and battery assembly. The assembly consists of the screen, battery, and frame together in one part. Be sure you have the right part before you begin the repair.

Before you begin, refer to the Samsung Self-Repair document for safety information.

If your battery is swollen, take appropriate precautions. Before disassembling your device, completely discharge the battery. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

Note: Retaining water resistance after the repair will depend on how well you reapply the adhesive, but your device will lose its IP (Ingress Protection) rating.

Some images in this guide may show minor discontinuities. They should not affect the overall guide procedure.

What you need

Step 1

              Eject the SIM Tray

Insert a SIM card eject tool, 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 gasket are mounted out of harm’s way.
Press in firmly to eject the tray.

Step 2

              Remove the SIM Tray

Remove the SIM card tray.
The SIM card will fall out of the tray easily.
When you reinsert the SIM card, ensure that it is in the proper orientation relative to the tray.
A thin rubber gasket around the SIM tray provides water and dust protection. If this gasket is damaged or missing, replace the gasket or the entire SIM tray to protect your phone’s internal components.

Step 3

              Heat the bottom edge

Unplug and power off your phone before you begin.
Heat an iOpener and apply it to the back cover’s bottom 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.

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.

Step 4

              Separate the bottom edge adhesive

Apply a suction cup to the back of the phone, as close to the center of the bottom edge as possible.
If the back cover is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken cover.
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 of reheating with the iOpener and separating with the suction cup before you get it right.
If you are having trouble creating a gap, apply more heat to the edge and try again.
Do not apply excessive force with the pick, or you risk cracking the back cover glass.

Do not apply excessive force with the pick, or you risk cracking the back cover glass.

Step 5

              Slice the adhesive

Slide the pick back and forth along the bottom edge to slice through the adhesive.
Do not attempt to cut the adhesive near the corners of the phone where the glass is curved or you risk cracking the glass panel.
Leave your opening pick in the seam to prevent the adhesive from resealing.

Step 7

              Separate the left edge adhesive

Apply a suction cup to the back of the phone, as close to the center of the left edge as possible.
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.
As the glass on this edge is curved, you won’t be able to insert this pick very far. As long as the very tip of the pick is underneath the glass’s edge, you will be able to proceed.
Due to tight tolerances, this may take multiple attempts.
If you are having trouble creating a gap, apply more heat to the edge and try again.
You can try also applying a few drops of high concentration (over 90%) isopropyl alcohol into the seam to help loosen the adhesive.

Gradually slide the pick from the right edge of the device around the top right corner.
Continue slicing along the top edge to fully separate the back cover adhesive.
If the slicing becomes difficult at any point, stop and reapply heat before continuing.

To reassemble your device, follow the instructions in reverse order and perform the opposite actions, e.g., “reattach” instead of “removing.” Skip steps that use heating and prying, and pay close attention to the 📌 bullets as you work through the steps.

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

After you’ve completed the repair, download the Samsung Members App from the Galaxy Store or the Play Store, and Samsung Self-Repair document (beginning page 10) to make sure your device is fully functional.
