Why can't people hear me unless I'm on speaker

Hi,

If you can be heard when using the speakerphone, there may be a problem with the phone’s internal microphone (loose or faulty?) or maybe the voice inlet hole, located on the bottom edge of the phone may be blocked by lint etc.

Use a strong light and a magnifying glass to visually inspect the voice inlet hole.

If it appears to be blocked (or even if you can’t tell) do not use a pin or probe to try and clear it, as the microphone is directly behind the hole and may be damaged. Try using a vacuum cleaner to suck out any debris.

If the voice inlet hole is not blocked then the phone will need to be opened and the problem further diagnosed. It may be that the microphone is loose on the systemboard or that it is faulty.

Here’s a link to a video that shows how to replace the touchscreen in your phone.

I realize that this is not the problem with the phone but the video is useful as it shows how to open the phone so access to the microphone is possible.
