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,...

If the front camera stopped working after a battery replacement, but Face ID still works, it’s likely a connection issue rather than a hardware failure. Here are a few things to check: 1. Reseat the Front Camera Flex Cable Since the front camera and Face ID share the same flex cable, it’s possible that the camera’s connection is loose. Try carefully reconnecting the front camera flex cable to the logic board. 2. Check for Damage to the Flex Cable If the cable was stretched, bent, or torn during the battery replacement, it could be damaged. Inspect it closely under good lighting. 3. Clean the Connectors Use 90%+ isopropyl alcohol and a soft brush to clean the connectors on both the logic board and the camera flex. Make sure it’s fully dry before reconnecting. 4. Check for Software Issues • Force restart: Press and quickly release Volume Up, then Volume Down, then hold the Power button until you see the Apple logo. • Check for updates: If the phone is running an outdated iOS version, updating might help. •...

It sounds like the bottom microphone might not be functioning properly after the screen replacement. Here are a few things to check: 1. Check for Obstructions – Make sure there’s no dust, debris, or adhesive (like from a screen gasket or epoxy) blocking the bottom microphone hole. 2. Inspect the Microphone Flex Cable – The Pixel 7 Pro’s bottom mic is part of a flex cable that could have been accidentally disconnected, damaged, or not seated properly during the repair. Try reseating the connector. 3. Test in Safe Mode – Booting into Safe Mode can rule out any software issues. If it works in Safe Mode, a third-party app might be interfering. 4. Check Sound Settings – Go to Settings > Sound & Vibration > Microphone to see if there’s anything unusual. 5. Try a Factory Reset – If the issue is software-related, a reset could fix it. Just make sure to back up data first. 6. Replace the Mic – If none of the above works, the microphone itself may be damaged and might need replacement.
