Now that we have gathered the necessary tools, let’s move on to the step-by-step process of replacing the screen of your Samsung Galaxy S3.

Step 1: Power Off the Device

The first step in replacing the screen of your Samsung Galaxy S3 is to power off the device completely. This is an important safety precaution that will prevent any accidental electrical shocks or damage during the repair process.

To power off the device, press and hold the power button located on the right-hand side of the phone. A menu will appear on the screen. Tap on the “Power Off” option to shut down the device.

If your device is unresponsive or the screen is completely broken, you can force a shutdown by pressing and holding the power button for about 10 seconds until the device powers off. This method is useful in situations where you cannot access the on-screen menu.

Once the device is powered off, wait for a few seconds to ensure that it is completely turned off before proceeding to the next step.

This step is crucial as it eliminates the risk of electrical shock or accidental damage to the internal components of the device. It’s always better to be safe and ensure that the device is powered off before starting any repair work.

Now that the device is powered off, we can move on to the next steps of the screen replacement process. Make sure to follow each step carefully to ensure a successful repair.

Step 2: Remove the Back Cover and Battery

Now that the device is powered off, it’s time to remove the back cover and battery of your Samsung Galaxy S3. This step will give us access to the internal components and prepare the device for further disassembly.

Follow these steps to remove the back cover and battery:

1. Flip the device over so that the back is facing up.
2. Locate the small notch or groove on the bottom-right corner of the device. This is where you’ll start removing the back cover.
3. Insert your fingernail, a plastic opening tool, or a guitar pick into the notch and gently pry the back cover away from the device.
4. Work your way around the edges of the device, slowly separating the back cover from the rest of the device. Be careful not to use excessive force, as this may damage the plastic clips holding the back cover in place.
5. Once the back cover is loosened, lift it off and set it aside.
6. With the back cover removed, you’ll now have access to the battery.
7. Locate the battery, which is a rectangular-shaped component usually at the top of the device.

With the display and digitizer cables disconnected, it’s time to remove the broken screen from your Samsung Galaxy S3. Removing the broken screen will make way for the installation of the new screen.

Follow these steps to remove the broken screen:

1. Inspect the broken screen to identify any adhesive or tape securing it to the device.
2. If there is adhesive or tape, use a heat gun or a hairdryer on a low setting to warm up the edges of the screen. This will soften the adhesive, making it easier to remove the screen.
3. Be careful not to overheat the device—excessive heat can damage internal components. Ensure that the heat is evenly distributed and avoid focusing the heat on one spot for too long.
4. Once the adhesive is sufficiently warmed up, insert a plastic opening tool or a guitar pick between the broken screen and the device’s frame.
5. Gently pry the screen away from the frame, gradually working your way around the edges of the device. Take your time and apply even pressure to prevent any damage to the underlying components.
6. As you work your way around, the adhesive should start to loosen, allowing the broken screen to separate from the device.
7. Continue to lift the screen slowly until it is completely detached.
8. Once the broken screen is fully removed, carefully place it aside for proper disposal.
9. Inspect the device’s frame to ensure that there are no remaining adhesive residues or other debris that could interfere with the installation of the new screen. If necessary, gently clean the frame using a microfiber cloth or a small brush.

Removing the broken screen requires patience and caution. Take your time to avoid any accidental damage to the device or its internal components.
