When Does This Chip Need to Be Replaced?
Hardware failure of this microchip typically causes distinct connectivity issues on your phone:
- Greyed-out Wi-Fi / Bluetooth toggle: The phone physically cannot switch on Wi-Fi or Bluetooth, or the slider switches back to “Off” automatically.
- No Networks Found: The phone stays permanently stuck searching for signals but finds nothing.
- Frequent Dropped Connections: Constant, unexplained disconnections even when sitting right next to your router.
Repair Information
- Mount Type: This is a Surface Mount Device (SMD) chip that is soldered directly onto the phone’s logic motherboard.
- Installation Requirements: Replacing it requires a micro-soldering technician with specific heat guns, solder paste, and a reballing stencil template (such as the Amaoe HI:2 Series Stencil). DIY replacement is not recommended as improper heat can permanently kill the entire phone motherboard.
