Samsung Galaxy Note 4 Antenna Replacement
If your Samsung Galaxy Note 4 won't connect to cellular or Wi-Fi networks, you might need to replace the antenna.
- Follow this guide for steps on replacing the antenna in your device.
Step 1 | Midframe
- Remove the 16 4.0mm Phillips #00 screws holding the midframe to the display assembly.
- Grasp the cap of the S Pen and pull it out from its slot in the midframe.
Step 2
Insert a plastic opening tool between midframe and display assembly.
- Work the plastic opening tool around phone's perimeter to break adhesive.
- This adhesive is weak, no heat gun needed for removal.
Be careful not to separate front glass panel from rest of display assembly.
Step 3
Use a plastic opening tool to release the clasps around the battery housing.
Step 4
Apply reasonable pressure to separate the midframe from the display assembly.
- Push on the battery housing to release the connection between the two parts.
- Remove and transfer the headphone jack assembly if not included with your new midframe, using plastic opening tools to pry it loose.
Step 5 | Detaching Antenna Connectors
Use tweezers to gently pull the connectors away from the phone.
- Identify the blue dot on the shorter connector, which should be positioned near the phone's bottom edge.
- Pull upwards on both connectors with tweezers until they detach completely.
