Samsung Android Phones Screen Cracked Repair: How to Fix It Yourself
A cracked Samsung Galaxy screen looks scary, but screen replacement is one of the most common phone repairs in the world. If you buy a screen assembly that includes the frame, it makes the job much easier. This is a harder repair, but thousands of people do it every day with the help of a YouTube video for their specific model.
⚠️ Safety First
- Power off your phone and remove the SIM card before starting.
- Wear safety glasses — cracked glass can flake off in sharp pieces.
- Be extremely careful around the battery. Samsung batteries can ignite if punctured.
- Use a heat gun on LOW setting or a hair dryer. Too much heat can damage the AMOLED display underneath.

Step-by-Step Repair
- 1
Back up your data and power off the phone
Before you start, back up everything to Google Drive or a computer. Power off the phone completely and remove the SIM card tray. You don't want to lose your photos and contacts if something goes wrong.
- 2
Heat the back panel to loosen the adhesive
Use a hair dryer on high or a heat gun on low for about 2-3 minutes on the back glass. The goal is to soften the glue holding the back cover on. It should feel hot but not too hot to briefly touch. Apply the suction cup to the back and gently pull while sliding a plastic opening pick into the gap.
- 3
Remove the back panel and disconnect the battery
Slide the plastic pick around all edges to cut through the adhesive. Remove the back panel. Inside, you'll see screws holding down a metal plate over the battery connector. Remove those screws and use a plastic spudger to gently pop the battery connector off the motherboard. This is crucial for safety.
- 4
Disconnect all ribbon cables
Carefully disconnect the display cable, camera cables, and any other ribbon cables connected to the motherboard. Take a photo at each step so you remember where everything goes. Remove any screws holding brackets or metal plates in place. Keep screws organized — a magnetic mat or labeled tape helps.
- 5
Transfer components to the new screen assembly
If you bought a screen with frame, transfer the motherboard, cameras, battery, charging port, and other components from the old frame to the new one. If you bought just a screen, you'll need to separate the old screen from the frame using heat and a pick, then attach the new screen. The frame version is much easier.
- 6
Reconnect everything and test
Reconnect all ribbon cables, making sure each one clicks into place. Reconnect the battery. Before sealing the phone, power it on and test: does the screen work? Does touch work everywhere? Do the cameras work? Test the speakers and charging port too.
- 7
Seal the phone back up
Once everything checks out, apply new adhesive strips or a thin line of B-7000 glue around the edges of the back panel. Press the back cover into place firmly and let it set for at least 30 minutes. Avoid getting the phone wet for 24 hours — the water resistance is reduced after opening.
If That Didn't Work
- If the screen is cracked but still fully functional, you can apply a tempered glass screen protector on top to prevent further damage and keep using it.
- If the display shows colored lines or dead spots, the AMOLED panel underneath is damaged too — you need a full display assembly, not just the glass.
When to Call a Professional
This is a hard repair. Samsung charges $200–$350 for screen replacement. Third-party shops charge $100–$250 depending on the model. If you've never opened a phone before, watching a full teardown video for your exact model first is essential. If you're nervous about it, a repair shop is a good investment.
