The issue you're experiencing with your Motorola Moto G, where you can only hear and be heard when using the speakerphone during calls, can be caused by various factors. Here are some troubleshooting steps to help you identify and potentially resolve the problem:
Restart Your Phone: Begin by restarting your phone. Sometimes, minor software glitches can cause audio issues, and a simple restart may resolve them.
Check Volume Settings: Make sure that the call volume is turned up. During a call, use the volume buttons to increase the call volume to the maximum.
Remove Screen Protector or Case: Sometimes, screen protectors or cases can cover the microphone or speaker, affecting call quality. Remove any screen protector or case and test the phone without them.
Clean Microphone and Speaker: Dust, debris, or dirt can accumulate in the microphone or speaker grille. Use a small, soft brush or compressed air to clean these areas carefully.
Check for Software Updates: Ensure that your phone's operating system and apps are up to date. Software updates may include bug fixes that can resolve audio issues.
Test in Safe Mode: Boot your phone into Safe Mode to check if a third-party app is causing the problem. If the issue doesn't occur in Safe Mode, it's likely caused by an app you've installed. You can then uninstall recently added apps one by one to identify the culprit.
Clear Cache Partition: Clearing the cache partition can help resolve system-related issues. The exact steps may vary depending on your phone model, but it usually involves booting into recovery mode and selecting the "Wipe Cache Partition" option.
Factory Reset: As a last resort, if none of the above steps work, you can perform a factory reset on your phone. Be sure to back up your important data before doing this, as it will erase all data on your device.
Hardware Check: If the problem persists after trying all the software-related solutions, it's possible that there is a hardware issue with the phone's speaker or microphone. In this case, you may need to contact Motorola customer support or visit a service center for repairs.
Please note that performing a factory reset should be a last resort, and you should only do it if you've exhausted all other troubleshooting options, as it will erase all your data and settings on the device. If the problem remains unresolved after trying these steps, it's best to seek professional assistance to diagnose and fix the issue.
