Samsung Galaxy Nexus Power Button Replacement
Since my power button stopped working and the device is out of warranty, I've replaced it myself.
- I hope this guide helps you do the same if your power button fails.
Step 1 | Power Button
Replace malfunctioning power button with:
- A replacement power flex cable
- A small Phillips head screwdriver
- A plastic opening tool
- (Optional) A tweezer
Note: A scalpel is not essential but may be helpful in tight spaces.
Step 2
- Remove the back cover, including the battery and sim-card.
- Disconnect the screws: remove 6 (or 7 for CDMA) screws holding the phone's housing in place.
Step 3
Avoid applying excessive force — risk of damage.
- Use a opening tool to pry off the housing along its edge.
- Once one side is removed, use your hands to gently release the other side.
Step 4
Remove the various connectors using your opening tool.
Step 5
Use a scalpel to carefully remove glued on volume- and power button flex cables without cutting the cable itself.
- Use the scalpel to pry out the vibrator.
- A spudger is a more suitable tool for this step, but a scalpel may be used as an alternative if one is not available.
Step 6
Ensure the motherboard clears any cables as you remove it.
- Replace the front-facing camera if desired.
- The back-facing camera can also be replaced at this time.
We will not be addressing these components in this guide, focus on replacing the malfunctioning power button instead.
Step 7
Be careful when opening the latch, as prying at the wrong part may cause no harm but waste time.
- Open the black latch with your opening tool.
- Use tweezers to carefully remove and replace the power button flex cable.
- Reclose the latch in its original position once the replacement is complete.
Step 8
Reassemble by placing the motherboard back into the device.
Ensure the flex cable is not caught underneath the motherboard.
Step 9
Reconnect the connectors, cable, and vibrator to the motherboard and housing using your fingers.
- You should hear a snap when attaching each connector securely.
- When reconnecting the coaxial cable, use gentle pressure, as it may be difficult to reattach – keep trying if needed.
Step 10
Align the flex cables carefully and secure them with any remaining adhesive.
Do not worry if cables appear loose – they will be secured by the case once reassembled.
Step 11
Reattach the housing. You should hear two distinct snaps.
- Replace the screws.
- Reinsert the battery and sim-card.
Step 12
Press the newly installed power button to turn on the device.
Be prepared for potential issues if the power button was not replaced correctly, leading to further troubleshooting or repair.
The Nexus logo should appear on the AMOLED display when the device powers up successfully.
