Removing the Old LCD

Now that you’re prepared, it’s time to remove the old LCD from your iPhone 4S. This step requires patience and precision, so let’s go through it step-by-step:

1. Remove the Pentalobe Screws: Start by removing the two pentalobe screws located next to the charging port at the bottom of the device. Be sure to keep these screws in a safe place!
2. Use the Suction Cup: Attach the suction cup near the home button, pulling gently to create a gap between the front glass and the rear casing. This will make it easier to fit your opening tool in.
3. Insert the Opening Tool: Carefully slide a plastic opening tool into the gap. Gently pry the front display away from the rear casing. Take your time—this part can be tricky!
4. Disconnect the Cables: Once the LCD is lifted, you’ll see several connectors. Use your tweezers to gently lift the metal brackets and disconnect the cables from the motherboard. Note the order in which you disconnect them; this will help during reassembly.
5. Remove the Old LCD: Finally, carefully lift the old LCD away from the frame. If it’s stuck, gently wiggle it free, but avoid using excessive force to prevent damage.

With the old LCD removed, you’re one step closer to revitalizing your iPhone 4S! Just remember to keep everything organized as you transition to installing the new screen.

7. Testing the New LCD

Now that you've successfully installed the new LCD on your iPhone 4S, it's time to ensure everything is functioning properly. Testing the new screen is a crucial step that can help you catch any issues before you seal everything back up.

Here’s a simple checklist to follow when testing your new LCD:

• Power On the Device: Press and hold the power button until the Apple logo appears. If the screen lights up, that’s a great first sign!
• Check Touch Sensitivity: Use your finger to swipe across the screen. Make sure that every area responds well to your touch. If some areas are unresponsive, you may need to reseat the LCD.
• Visual Inspection: Look for any dead pixels or discoloration. You can test this by displaying different colors or images. There are also apps available that can help test for dead pixels.
• Test the Display Brightness: Adjust the brightness settings and ensure the screen can go from dim to bright without any flickering.
• Check for Proper Alignment: Make sure there aren’t any gaps between the LCD and the frame of the phone. The screen should sit flush against the body.

After running through this checklist, if everything looks good, you're ready to reassemble your phone! But if you find any issues, it might be worth troubleshooting further before sealing it up.
