Replacing the LCD display on your Samsung Galaxy Express Prime can seem like a daunting task, but with the right tools, patience, and guidance, it's a manageable DIY project. This article aims to provide you with a detailed, step-by-step guide, complete with visual aids and additional tips to ensure a successful repair.
Several reasons might prompt you to replace your Samsung Galaxy Express Prime's LCD display:
- Cracked or Shattered Screen: This is the most common reason. A cracked screen not only impairs visibility but can also pose a risk of cuts or further damage to the phone's internal components.
- Dead Pixels: These are small, dark spots on the screen that don't display any color. While a few dead pixels might be tolerable, a large cluster can be distracting and affect the overall viewing experience.
- Display Issues: These can include flickering, discoloration, or a completely black screen, even though the phone is powered on.
- Touchscreen Unresponsiveness: Sometimes, the LCD and touchscreen are fused together. If your touchscreen is not responding to touch, replacing the entire display assembly might be necessary.
Before you begin, gather all the necessary tools and ensure you have a suitable workspace.
Tools Required:
- New LCD Screen Assembly: Purchase a replacement LCD screen specifically designed for the Samsung Galaxy Express Prime (J320A).
- Small Phillips Head Screwdriver: For removing screws inside the phone.
- Plastic Prying Tools: These are essential for safely separating the screen from the phone body without causing damage[7].
- Spudger: A specialized tool for disconnecting ribbon cables and prying open connectors[1].
- Heat Gun or Hair Dryer: To soften the adhesive holding the screen in place[4].
- Suction Cup: To help lift the screen assembly.
- Fine Tip Curved Tweezers: Useful for manipulating small components[1].
- Playing Cards or Thin Plastic Cards: To help slice through the adhesive[1].
- SIM Card Ejection Tool: To remove the SIM and microSD cards[1].
- Precision Knife: To create initial space for inserting a playing card[1].
- Red Adhesive Roll: To re-seal the new screen to the phone[1].
Workspace Preparation:
- Clean and Well-Lit Area: A clean workspace will prevent small parts from getting lost. Good lighting is crucial for seeing what you're doing.
- Anti-Static Mat: This will protect the phone's sensitive components from static electricity.
- Organization: Keep a small container or magnetic pad to organize screws and small parts as you remove them. This will prevent confusion during reassembly.
Precautions:
- Power Off Your Device: Before starting any repair, power off your Samsung Galaxy Express Prime to prevent electrical damage.
- Static Electricity: Ground yourself to avoid static discharge, which can harm the phone's internal components.
- Patience: This repair requires patience and a steady hand. Rushing can lead to mistakes and further damage.
- Warranty: Be aware that performing this repair yourself will likely void your manufacturer's warranty[4].
Use the SIM card ejection tool to remove the SIM and microSD card trays from the side of the phone[1]. Set them aside.
Apply heat to the edges of the screen using a heat gun or hair dryer. Keep the heat moving and avoid concentrating it on one spot for too long. The goal is to soften the adhesive securing the screen[1][4].
Use a precision knife to gently create a small gap between the screen and the frame[1]. This will allow you to insert a playing card or thin plastic card.
Insert a playing card or thin plastic card into the gap and gently slide it around the edges of the screen to cut through the adhesive[1]. Apply heat as needed to keep the adhesive soft. Be careful not to insert the card too deeply, as this could damage the LCD or internal components.
Once you've sliced through the adhesive on all sides, use a suction cup to gently lift the screen assembly[4]. If the screen doesn't lift easily, double-check that you've cut through all the adhesive and apply more heat if necessary.
With the screen lifted slightly, you'll see a bracket covering the display cable connector on the motherboard[1]. Remove the bracket screws and detach the bracket. Use a spudger to gently pry up the display cable connector from the motherboard.
Now that the display cable is disconnected, you can safely remove the screen assembly from the phone[1].
Pry open the back cover, and you'll see the battery. Gently remove the battery[2].
Remove all the Phillips head screws that secure the midframe to the phone[4]. Use a plastic prying tool to gently separate the midframe from the phone body.
You'll need to disconnect any other cables or connectors that are attached to the motherboard, such as the front-facing camera and proximity sensor cables. Use a spudger to gently pry up these connectors.
Carefully lift the motherboard out of the phone body. Be sure to note its orientation so you can reinstall it correctly.
If your replacement screen assembly doesn't include components like the earpiece speaker or front-facing camera, you'll need to carefully transfer them from the old screen to the new one. Use a heat gun to soften the adhesive and a plastic prying tool to gently remove the components.
Connect the display cable to the motherboard and secure it with the bracket[4]. Carefully align the new screen assembly with the phone body and gently press it into place.
Reassemble the phone by reversing the steps you took to disassemble it. Make sure all cables are properly connected and all screws are securely tightened.
Before fully reassembling the phone, power it on and test the new screen to make sure it's working properly. Check for any dead pixels, discoloration, or touchscreen issues.
Once you've confirmed that the new screen is working correctly, finish reassembling the phone. Apply new adhesive around the edges of the screen and press it firmly into place[1].
- Take Your Time: Don't rush the repair process. Work carefully and methodically to avoid mistakes.
- Refer to Videos: Watch videos of the repair process to get a better understanding of what's involved[1][4].
- Use the Right Tools: Using the correct tools will make the repair easier and prevent damage to the phone.
- Keep Screws Organized: Keep track of all the screws you remove and label them if necessary. This will make reassembly much easier.
- Test Before Reassembling: Before fully reassembling the phone, test the new screen to make sure it's working properly.
- Screen Not Working: Double-check that the display cable is properly connected to the motherboard.
- Touchscreen Not Working: Make sure the touchscreen cable is properly connected.
- Phone Won't Power On: Ensure the battery is properly connected and charged.
- Screen Adhesive: If the screen adhesive doesn't stick properly, consider purchasing a stronger adhesive to re-seal it.

Replacing the LCD display on your Samsung Galaxy Express Prime is a challenging but rewarding DIY project. By following this comprehensive guide and taking your time, you can save money and gain a sense of accomplishment. Remember to exercise caution, use the right tools, and refer to videos for additional guidance.
You can purchase a replacement LCD screen from online retailers like Amazon, eBay, and specialized phone repair parts websites. Make sure to buy a screen specifically designed for the Samsung Galaxy Express Prime (J320A).
The cost of a replacement LCD screen typically ranges from $20 to $50, depending on the quality and vendor. If you choose to have a professional repair shop replace the screen, the total cost could range from $80 to $150, including labor.
In most cases, the glass and LCD are fused together, so you'll need to replace the entire LCD assembly. Separating the glass from the LCD is a difficult and risky process that can easily damage the LCD.
You can recycle your old LCD screen at electronic waste recycling centers. These centers will safely dispose of the screen and recover any valuable materials.
It is generally not safe to use a cracked phone screen, as it can pose a risk of cuts and further damage to the phone's internal components. It's best to replace the screen as soon as possible.
