Cracked displays, dead touch zones, or vertical green lines indicate that your Samsung Galaxy S25 FE needs a new screen. This guide walks you through replacing the display assembly safely and effectively. You will be transferring your original internal components into a new screen and frame assembly, which is the most reliable repair method.
Required Tools
- 1
Heat the Back Cover
- Apply heat to the edges of the back glass using a heat gun to soften the adhesive.
- Keep the temperature moderate to avoid damaging the battery or camera lenses.
- 2
Slice the Adhesive
- Place a suction cup near the bottom edge and pull up gently to create a small gap.
- Insert a plastic opening pick and carefully slice around the perimeter to separate the back cover from the frame.
- 3
Remove the NFC Coil and Bracket
- Unscrew the Phillips #000 screws securing the metal bracket and NFC wireless charging coil.
- Lift the assembly out with tweezers to expose the motherboard connections.
- 4
Disconnect the Battery
- Always disconnect the power before handling other internal components to prevent short circuits.
- Use a plastic spudger to pry up the battery connector from the motherboard safely.
- 5
Remove the Loudspeaker and Sub-board
- Take out the screws holding the bottom loudspeaker assembly in place and remove it.
- Disconnect the interconnect flex cables and carefully extract the USB-C charging sub-board.
- 6
Extract the Motherboard and Cameras
- Disconnect the display cable and carefully lift out the main motherboard.
- Note that the front camera is glued to the frame and requires controlled heat for safe removal.
- 7
Remove the Battery
- Apply a few drops of 99% isopropyl alcohol around the battery edges to dissolve the underlying adhesive.
- Wait a couple of minutes before gently prying the battery out, being extremely careful not to puncture the cell.
- 8
Transfer Components to the New Frame
- Place the battery, motherboard, sub-board, and cameras into your new screen assembly.
- Reconnect all flex cables securely and ensure the front camera sits perfectly flush.
- 9
Reassemble and Seal the Device
- Screw the loudspeaker and NFC bracket back into their original positions.
- Apply new pre-cut adhesive to the back cover, press it firmly onto the frame, and clamp it while the adhesive cures.

FAQ
Will this repair compromise the water resistance of my phone?
Yes, opening the device breaks the factory waterproof seal. You must apply new pre-cut adhesive carefully to restore basic moisture resistance.
Should I buy a screen with the frame included?
Purchasing a screen pre-installed in a new frame is highly recommended. It makes the repair much easier because you do not have to separate the shattered OLED panel from the old metal chassis.
What should I do if the back glass refuses to separate?
Apply more heat to the stubborn area and use extra isopropyl alcohol on your opening pick. Never force the glass, as it can shatter and cause injury.
Do I need to transfer the old thermal paste?
It is best practice to clean off the old thermal paste and apply a small amount of new paste to the motherboard to ensure optimal cooling.
