Having the right tools will greatly assist in making the process smoother and safer.
Preparing for Screen Replacement
Before starting the replacement, it’s essential to prepare properly. Follow these steps to ensure a successful repair.
1. Backup Your Data
Before you begin disassembling your device, it’s crucial to back up your data. Though this process should not affect your data, it’s better to be safe. Use Samsung Cloud or Google Drive to back up your photos, contacts, and other important files.
2. Power Off Your Samsung S20
Always turn off your device before beginning any repair. Powering down helps prevent potential electrical short circuits and protects the internal components.
3. Work in a Clean, Well-Lit Space
A clean, organized workspace minimizes the risk of losing small parts and keeps your environment safe. Make sure to have adequate lighting so you can see what you are doing clearly.
Step-by-Step Instructions to Change Your Samsung S20 Screen
Now that you’re prepared, let’s get into the actual process of replacing the screen.
Step 1: Remove the Back Cover
The first step is to carefully remove the back cover to access the internal components.
1.1. Heat the Back Cover
Using a heating pad or hairdryer, apply gentle heat to the back cover for about 30 seconds. This soften the adhesive, making it easier to remove.
1.2. Prying Off the Back Cover
Using a plastic prying tool, gently insert it between the back cover and the frame. Carefully slide it around the edges to detach the adhesive. Be mindful not to use excessive force, as it could crack the glass.

To ensure your safety, you need to disconnect the battery before working on other components.
2.1. Locate the Battery Connector
With the back cover removed, locate the battery connector on the circuit board, usually at the bottom of the phone.
2.2. Disconnect the Battery
Gently lift the connector using your plastic prying tool. This step is crucial in preventing any electrical shocks during the replacement process.
Step 3: Remove the Screen Assembly
Now it’s time to remove the screen assembly from the frame.
3.1. Heat the Screen Edges
Apply heat to the edges of the screen in the same manner as you did for the back cover. This softens the adhesive, making it easier to remove.
3.2. Prying the Screen Assembly
Using a plastic prying tool again, carefully insert it between the screen and the frame. Slowly work your way around the edges to release the adhesive. Again, take care not to apply too much force.
3.3. Disconnect Screen Cables
Once the screen is loose, you will find several connectors attached to the motherboard. Carefully lift and disconnect these cables using your tweezers or plastic prying tool.
Step 4: Install the New Screen

What tools do I need to change the Samsung S20 screen?
To change the Samsung S20 screen, you will need several tools, including a heat gun or hairdryer, a plastic opening tool, a Phillips screwdriver, and a suction cup. Using a heat gun or hairdryer will help you soften the adhesive holding the screen in place, making it easier to remove. A plastic opening tool will help you pry apart the screen from the frame without damaging the components, while a Phillips screwdriver will be necessary for removing screws around the screen.
Additionally, having tweezers handy can help with maneuvering small parts, and a magnetic mat can help keep screws organized. It’s also advisable to have an anti-static wrist strap to prevent any static damage to your phone’s internal components while you work on it. Gathering all these tools beforehand will make the process smoother and more efficient.
Is it necessary to turn off the phone before changing the screen?
Yes, it is crucial to turn off your Samsung S20 before starting the screen replacement process. Powering off the phone minimizes the risk of accidental electrical shorts, which can occur if the device’s circuits are still active while being disassembled. Turning off the phone protects both you and the device from potential damage and ensures that you work safely.
Additionally, shutting down the phone prevents any unsaved data from becoming corrupted during the replacement. To power off your device, press and hold the power button until the shutdown menu appears, then select “Power off.” This simple step helps ensure a safer and more effective screen replacement experience.
Can I replace the screen myself, or should I seek professional help?
While it is possible to replace the Samsung S20 screen yourself, it requires a certain level of technical skill and experience with electronics repair. If you are comfortable with DIY projects and have the right tools, you can follow a step-by-step guide to replace the screen on your own. Many people successfully complete repairs at home, finding it a rewarding experience.
However, if you are unsure about your ability to perform the repair or if the phone has warranty coverage, it may be safer to seek professional help. A professional repair service can handle the replacement quickly and effectively, reducing the risk of further damage to your device. Ultimately, the decision depends on your confidence and comfort level with electronic repairs.
What should I do if the screen doesn’t turn on after replacement?
If the screen does not turn on after you complete the replacement, there may be several issues to address. First, ensure that all connections between the screen and the motherboard are secure. You might have missed reconnecting a cable or connected it improperly during reassembly. Gently re-open the device to check the connections and ensure everything is firmly in place.
If the connections are secure and the screen still does not turn on, it might be due to a defective replacement screen or other underlying issues. In this case, testing the old screen, if still functional, could help identify if the new screen is indeed faulty. If issues persist, contacting a professional technician may be necessary to diagnose and fix any internal problems.
Will changing the screen myself void the warranty?
In most cases, if you open your Samsung S20 and replace the screen yourself, it will likely void any existing warranty. Manufacturers typically offer warranties that cover defects in manufacturing but may not cover damage that occurs from user repairs. It’s essential to read through Samsung’s warranty terms to understand which repairs could affect your coverage.
However, if the phone is already out of warranty or if you’re willing to take the risk, DIY screen replacement can be a viable option. Just ensure you have the proper skills and tools. If you are concerned about warranty implications, consider consulting a professional repair service that might maintain your warranty while addressing your issue.
How long does it take to change the Samsung S20 screen?
Changing the Samsung S20 screen can take anywhere from 30 minutes to a couple of hours, depending on your level of experience and comfort with the repair process. If you are familiar with the process and have all the necessary tools, you might complete it more quickly. However, if this is your first time, it’s wise to allow extra time for careful handling and troubleshooting.
Additionally, the time it takes can vary based on factors such as the quality of the replacement screen and the condition of the device. If you encounter difficulties, like stuck adhesive or complex connections, you may find the process taking longer. It’s important to work at your own pace to ensure a successful replacement without rushing.
Where can I buy a replacement screen for my Samsung S20?
You can purchase a replacement screen for your Samsung S20 from various sources, including online retailers, electronics repair shops, or authorized Samsung service centers. Websites like Amazon, eBay, and specialized parts suppliers often have a wide selection of replacement screens compatible with the S20. When buying online, make sure to check reviews and ratings to ensure you receive a quality product.
Alternatively, if you’re unsure about purchasing the correct part, visiting a professional repair shop may help. They can source the appropriate replacement screen for you and may even offer to perform the installation. Always verify the credibility of the vendor and consider the warranty or return policy on the screen to protect your investment.
