How to Change Display on Samsung J7 Prime: The Ultimate Guide

If you’re facing a cracked, shattered, or unresponsive display on your Samsung J7 Prime, you’re not alone. This is a common issue that can happen to anyone. Thankfully, replacing the display is a relatively straightforward process, and you can do it yourself to save some money. This guide will walk you through every step, from gathering the necessary tools to installing the new display.

Why You Might Need to Change the Display

Before we dive into the steps, let’s quickly understand why you might need to replace the display on your Samsung J7 Prime:

• Cracked or shattered screen: This is the most common reason. A drop or impact can easily crack the glass, making the screen unusable.
• Unresponsive touch: If your touch input isn’t registering properly, the digitizer (the touch sensor layer) might be damaged.
• Black or blank screen: A faulty display can cause the screen to go black or show nothing at all.
• Flickering or distorted display: Issues with the display itself can lead to flickering or distorted images.

Essential Tools and Materials

Before you start, make sure you have everything you need:

• Replacement display assembly: This is the most crucial part. Ensure you purchase a compatible display assembly for the Samsung J7 Prime.
• Phillips screwdriver: You’ll need this to remove the screws holding the phone together.
• Spudger: A spudger is a plastic tool used to pry open the phone without damaging the components.
• Heat gun or hairdryer: This is optional but helpful for softening the adhesive holding the display in place.
• Tweezers: These will come in handy for removing small parts.
• Anti-static wrist strap: This helps prevent static electricity from damaging the phone’s components.
• Cleaning cloth: This is for cleaning the phone and the new display.

Step 1: Preparation and Safety

1. Back up your data: Before you start, back up all your important data to your computer or cloud storage. This is essential in case something goes wrong during the repair.
2. Power down your phone: Turn off your Samsung J7 Prime and remove the SIM card and SD card if you have them.

2. Disconnect other connectors: Disconnect any other connectors connected to the display assembly, such as the volume buttons, power button, and front camera.
3. Heat up the display: If the display is glued securely, use a heat gun or hairdryer to soften the adhesive. Be careful not to overheat the phone.
4. Pry off the display: Use a spudger to gently pry the display assembly off the phone. Start from the edges and work your way towards the center. Be careful not to apply too much force.
5. Remove the old display: Once the display is loose, carefully remove it from the phone.

Step 4: Installing the New Display Assembly
