Phone Tools for Samsung Galaxy S25 Ultra Screen Replacement
Replacing the screen on a Samsung Galaxy S25 Ultra requires precision, the right tools, and a steady hand. Here are the essential tools you’ll need:
1. Pentalobe Screws Driver
Samsung devices typically use pentalobe screws to secure the device. A Pentalobe screwdriver is required to open the device without causing any damage.
2. Plastic Pry Tools
Plastic pry tools help you open your phone without damaging the screen or frame. These tools allow you to carefully detach the display from the body without leaving marks or scratches.
3. Suction Cup Tool
A suction cup tool is crucial for lifting the screen off the body without using excessive force. It provides a secure grip to gently separate the screen from the rest of the phone.
4. Tweezers
Tweezers are handy for handling delicate components like the adhesive or small parts inside the phone that need careful attention.
5. Heat Gun or Heating Pad
The adhesive that holds the screen in place can be quite strong. A heat gun or heating pad softens the glue and makes it easier to separate the screen from the device. Be sure to apply heat evenly to avoid damaging the internal components.
6. SIM Card Ejector Tool
Before starting the replacement, you need to remove the SIM card tray. The SIM card ejector tool is a small, essential tool for safely ejecting the tray.
7. Plastic Spudger
The plastic spudger is another non-marring tool that is used to pry open tight spots without damaging the phone’s internal components.
8. Replacement Adhesive
When reinstalling the screen, you’ll need new adhesive strips to secure the screen in place. OEM replacement adhesive ensures that the screen sticks properly without leaving any gaps or imperfections.
9. ESD-Safe Mat & Wrist Strap
Working with electronics can be hazardous due to electrostatic discharge (ESD). Using an ESD-safe mat and a wrist strap will protect your phone’s internal parts from static damage during the repair process.
Step-by-Step Guide to Replacing the Screen
Now that you have the right tools, here’s a basic overview of how to replace the screen on your Samsung Galaxy S25 Ultra.

2. Remove the SIM Card Tray
Use the SIM card ejector tool to remove the tray.
3. Heat the Screen
Apply gentle heat to the edges of the phone using a heat gun or heating pad. This will soften the adhesive holding the screen in place.

Attach the suction cup tool to the screen and gently lift it. Be cautious not to apply too much force.
5. Insert a Pry Tool
Once the screen is slightly lifted, insert a plastic pry tool to separate the screen from the device. Work your way around the device carefully.
6. Disconnect the Battery
After removing the screen, locate the battery connector and disconnect it to avoid short-circuiting the phone during the repair.
7. Remove the Broken Screen
If there is any remaining adhesive or pieces of the broken screen, remove them with tweezers or a spudger.

Apply the new adhesive to the edges of the new screen and connect it to the phone. Carefully press the new screen into place.
9. Reconnect the Battery
Once the screen is in place, reconnect the battery.
10. Test the Device
Before sealing the phone, power it on to test if the new screen works correctly. Check for functionality such as touch responsiveness, display brightness, and color accuracy.

Once everything is functioning properly, reassemble the phone by securing the screws and sealing the device.
