Samsung Galaxy J3 (2018) Screen Replacement
Step 1 | Remove The Battery
Locate the back panel and its corresponding removal point at the lower right corner.
- Remove the back panel using a suitable tool, taking care not to damage surrounding components.
- Disconnect the battery connector and gently lift out the battery, being mindful of the dimple on its bottom edge.
Step 2 | Quick Notes:
Locate the panel connector on the back of the device.
- Since it's situated near the panel, no screws are required for removal.
- When cutting out the old screen, be mindful that this connector is at the top edge.
To preserve the old screen as a spare, avoid the top edge while slicing adhesive.
Step 3 | Prepare the old screen for removal
If your device has a cracked screen, apply packing tape around it to secure loose glass and create a stable surface.
- Remove any existing screen protectors.
Step 4 | Applying Heat
Apply even heat using an iOpener, heatgun, or similar tool.
- Heat the device until it is warm to the touch.
- Avoid focusing on a single spot for too long.
- Goal: weaken adhesive bond, not overheat device.
Step 5 | Working along the bottom
Use a suction cup to pry up near the bottom of the screen, creating a good gap.
- Insert an opening pick into the gap, being mindful of the home button.
- Be careful not to go too deep near the capacitive buttons.
- Add another opening pick and position them on opposing corners.
Step 6 | Working along the sides
Work from both edges towards the center, keeping the top cable in mind.
- Hold your pick at a downward angle to access space below the screen.
- The display is shielded; you won't damage components behind it.
Step 7 | Getting the top of the display
Do not damage the display cable — risk of costly repair.
- Use a pick to gently work around the top edge (no deeper than 3mm) to clear the display cable.
Disregard this step if you plan to replace the screen with a new one.
- Reheat and carefully sever remaining adhesive along the top bezel, but do not go deeper than 5mm.
Step 8 | Remove the display
Apply heat near the top of the display again.
- Open the phone from the bottom to the top.
- Leave the top edge of the old screen's connector hanging off, as it is too short to remove completely.
Take care not to damage the cable.
Step 9 | Removing the Connector
Use an opening tool to remove the shield covering the press-fit connector.
- Pry out the press-fit connector using a spudger.
