Before diving into the screen replacement process, you need to acquire the right tools and materials. Here’s a list of what you will need:
- Replacement Screen: Ensure that you purchase a quality replacement screen compatible with the Samsung Galaxy S7.
- Heat Gun or Hair Dryer: This will help to soften the adhesive used to secure the screen to the phone body.
- Suction Cup Tool: This tool will assist you in lifting the old screen off the device.

Preparing the Samsung S7 for Screen Replacement
Preparation is key to a successful screen replacement. Follow these steps to get your device ready:
Step 1: Power Off Your Device
Before you start, it’s crucial to turn off your Samsung S7 to prevent any electrical damage or shorts during the replacement process. Hold the power button and select “Power Off” from the menu.
Step 2: Remove the SIM Card Tray
Using a SIM card ejector tool or a paperclip, remove the SIM card tray from the side of the device. This step will prevent any damage to the tray during the screen replacement.
Step 3: Warm Up the Display
Utilize a heat gun or hairdryer, set to a low temperature, to gently warm the edges of the screen. This step is essential as it softens the adhesive holding the screen in place. Make sure not to overheat the area; a few seconds will suffice.
Removing the Damaged Screen
Once you have prepared the device, it’s time to remove the damaged screen.
Step 4: Creating a Gap
Using a plastic pry tool, gently insert it between the screen and the phone body. Start at the corner where the display meets the frame. Carefully work the tool around the edges, creating a gap.
Step 5: Lifting the Screen
Once you create a gap, attach the suction cup tool to the screen. Carefully pull on the suction cup while continuing to insert the plastic pry tool to separate the display from the body. Take your time with this step to avoid damaging internal components.
Step 6: Disconnecting the Screen
After lifting the screen, you will encounter a series of screws securing the connector to the motherboard. Using your Phillips or pentalobe screwdriver, carefully remove these screws. Once removed, gently disconnect the screen connector using tweezers.
Preparing the New Screen for Installation
Now that the damaged screen is removed, let’s prepare the new screen for installation.
Step 7: Cleaning the Phone’s Body
Before installing the new screen, make sure to clean the phone’s body with a lint-free cloth. Remove any dust or debris to ensure a secure seal when the new screen is installed.
Step 8: Peeling Off the Adhesive Tape
If your new screen does not come with adhesive pre-attached, you will need to apply adhesive tape along the edges of the new screen. Peel off the protective cover and apply the adhesive carefully along the edges, ensuring it covers the entire perimeter.
Installing the New Screen
It’s almost time to bring your Samsung S7 back to life with the new screen!
Step 9: Connecting the New Screen
Align the connector of the new screen with the motherboard. Gently push the connector into place until it clicks securely. Be cautious—forcefully handling the connector can cause damage.
Step 10: Securing the Screen
Once the connector is in place, use your screwdriver to reattach the screws you previously removed. Ensure that each screw is securely tightened but avoid over-tightening as it may cause damage.
Step 11: Positioning the New Screen
Carefully place the new screen onto the front of the device. Start by aligning it with the edges and ensure it fits snugly within the frame.
Final Steps: Testing and Sealing the New Screen
With the new screen installed, it’s crucial to test its functionality.
Step 12: Power On Your Device
Before sealing everything up, power on your Samsung S7 to check if the new screen works correctly. Verify touch responsiveness and screen clarity. If everything functions properly, you can proceed to seal the screen.
Step 13: Sealing the Screen
If you used adhesive tape, press down along the edges of the screen to ensure a secure bond. Once you confirm the adhesive’s reliability, allow it to set by avoiding any pressure to the screen for a few hours.
Step 14: Reinstalling the SIM Card Tray
Finally, reinstall your SIM card tray back into the device.
