Samsung Galaxy Z Flip7 FE Charging Port Repair
When your Samsung Galaxy Z Flip7 FE stops charging, drops the connection randomly, or fails to fast charge, the USB-C port is likely damaged or worn out. Replacing the charging port daughterboard restores full charging and data transfer capabilities for your device. This guide will walk you through safely opening the bottom half of your phone to install a new charging port module. Please work in a well-lit area and wear safety glasses to protect your eyes from shattered glass.
Required Tools
- 1
Heat the bottom glass
- Apply heat to the bottom back glass panel of the phone using a heat gun or iOpener.
- Keep the heat moving to soften the adhesive without melting the internal components.
- 2
Create an opening gap
- Place a suction cup near the bottom edge of the glass and pull up gently.
- Insert a plastic guitar pick into the small gap created between the glass and the metal frame.
- 3
Slice the adhesive
- Slide the guitar pick around the perimeter of the bottom glass panel to cut through the waterproof adhesive.
- Do not insert the pick too deeply to avoid damaging the internal cables.
- 4
Remove the bottom glass
- Carefully lift the bottom glass panel away from the phone once all the adhesive is cut.
- Set the glass aside in a safe place where it will not get scratched.
- 5
Unscrew the lower shield
- Use a Phillips #00 screwdriver to remove the screws securing the lower plastic shield and speaker assembly.
- Keep these screws organized on a magnetic mat so you do not lose them.
- 6
Disconnect the battery
- Use a plastic spudger to gently pry up and disconnect the lower battery connector from the motherboard.
- Disconnecting the power immediately prevents accidental short circuits while you work.
- 7
Remove the speaker assembly
- Pry up the plastic shield and loudspeaker assembly with a spudger and lift it out of the phone.
- This exposes the charging port daughterboard underneath.
- 8
Disconnect the flex cables
- Use the spudger to disconnect the main interconnect flex cable and the antenna cables attached to the charging port board.
- Handle the delicate antenna wires with tweezers to prevent tearing them.
- 9
Extract the old charging port board
- Remove any remaining screws holding the charging port board in place.
- Lift the old board out of the chassis using your spudger or tweezers.
- 10
Install the new charging port
- Place the new charging port daughterboard into the housing and secure it with its screws.
- Reconnect the antenna cables and the main interconnect flex cable firmly.
- 11
Reassemble the internal components
- Place the speaker assembly back over the charging board and secure it with the Phillips screws.
- Reconnect the lower battery flex cable to restore power to the bottom half of the device.
- 12
Seal the device
- Clean the old adhesive off the frame and apply a new pre-cut adhesive sheet.
- Press the bottom back glass firmly into place and apply steady pressure for a few minutes to ensure a tight seal.

FAQ
Why is my phone charging slowly after the repair?
Slow charging can occur if the interconnect flex cable is not seated properly. Open the device and ensure the cable is firmly snapped into place on both ends.
Will this repair fix moisture detection errors?
Yes. If your phone constantly displays a moisture warning even when dry, replacing the charging port board usually resolves the false sensor reading.
Is my phone still waterproof after this repair?
The factory water resistance is compromised once the device is opened. You must use high-quality replacement adhesive and apply it perfectly to restore basic water resistance, but you should avoid submerging the phone.
Can I just clean the port instead of replacing it?
You can try cleaning the port with a wooden toothpick and isopropyl alcohol first. If the pins are physically bent or the port remains unresponsive, a full replacement is required.
