When your Samsung Galaxy Z Flip7 rear cameras produce blurry images, fail to focus, or show a completely black screen, a camera module replacement is usually necessary. This repair involves entering the device through the upper back glass panel which houses the delicate cover screen. You will need a steady hand and patience to safely navigate the internal components without damaging the flexible display cables.
Required Tools
- 1
Power Off the Device
- Always begin by completely powering down your foldable phone to prevent electrical shorts.
- Wear an anti-static wrist strap to protect the sensitive internal components from static discharge.
- 2
Heat the Upper Back Panel
- Apply gentle heat to the upper rear glass panel using a heat gun or heating pad to soften the factory adhesive.
- Keep the heat moving constantly to avoid burning the cover screen display underneath the glass.
- 3
Slice the Adhesive
- Place a suction cup near the edge of the heated upper glass and pull up slightly to create a tiny gap.
- Insert a plastic guitar pick into this gap and carefully slide it around the perimeter to cut through the adhesive.
- 4
Disconnect the Cover Screen
- Lift the upper glass panel very slowly like a book to reveal the cover screen flex cable connected to the motherboard.
- Use a plastic spudger to gently pop the connector off its socket before completely setting the upper panel aside.
- 5
Remove the Motherboard Shield
- Locate the protective metal shield covering the main motherboard and battery connectors.
- Unscrew the Phillips screws securing this bracket and lift it out of the device with tweezers.
- 6
Disconnect the Batteries
- Safety is paramount when working inside modern smartphones.
- Use your plastic spudger to immediately disconnect both battery flex cables from the motherboard to ensure no power is flowing through the board.
- 7
Extract the Faulty Camera Module
- Locate the rear camera module and use a spudger to disconnect its flex cables from the motherboard.
- Carefully pry the old camera unit out of its housing using tweezers.
- 8
Install the New Camera
- Seat the replacement camera module into the empty housing and ensure it sits perfectly flush.
- Gently press the new camera flex cables down onto their motherboard sockets until they click securely into place.
- 9
Reconnect Power and Test
- Reconnect both battery flex cables and temporarily attach the cover screen cable to test the device.
- Power the phone on and open the camera application to verify that the new lenses focus correctly and produce clear images.
- 10
Seal the Device
- Once testing is successful, power the phone back down and reinstall the metal motherboard shield with its screws.
- Clean the old adhesive off the frame with isopropyl alcohol, apply new precut adhesive strips, and firmly press the upper back glass panel back into place.

FAQ
Will this repair fix a cracked camera lens glass?
If only the exterior glass covering the lens is cracked but the camera still takes perfect photos, you only need to replace the external lens cover. However, if the camera itself is damaged or has dust inside the sensor, you must replace the entire internal camera module.
Does opening the phone compromise its water resistance?
Yes, breaking the original factory seal will compromise the water resistance of your foldable device. You must apply high-quality replacement adhesive during reassembly to restore as much protection as possible.
Why do I need to disconnect both batteries?
The Galaxy Z Flip7 utilizes a dual-battery system with a cell in both the top and bottom halves of the phone. Disconnecting both ensures the motherboard is completely isolated from power, which prevents accidental short circuits during the repair.
Can I use a metal pry tool to remove the back glass?
You should strictly avoid using metal tools to pry the glass panels. Metal can easily scratch the aluminum frame, crack the glass, or sever the delicate cover screen flex cable hidden underneath.
