Where is Bluetooth antenna and can I replace it?

Yes, the Bluetooth antenna in the iPhone 14 is integrated into the upper antenna flex cable, which is located near the top right corner of the phone, close to the front camera and Face ID components. Since the camera was previously serviced, it’s very possible that the Bluetooth antenna was either disconnected, damaged, or not properly reinstalled during that repair.

Steps to Check and Replace the Bluetooth Antenna:

1. Check for Loose Connections

• Open the phone carefully and inspect the antenna flex cable near the front camera module.

• Make sure it’s securely connected to the logic board.

2. Inspect for Damage

• Look for any tears or bends in the antenna flex. Even a small tear can cause major Bluetooth issues.

3. Try a Software Reset

• Go to Settings > General > Reset > Reset Network Settings to see if that helps.

• Update iOS in case it’s a software issue.

4. Replace the Antenna Flex Cable

• If it’s damaged, you’ll need to replace it.

• Since Apple doesn’t provide official repair guides for this part, you’ll need to find a teardown that covers antenna locations.
