I can hear everything but no one can hear me

Hi,

Is the phone in a case at all?

If it is try using it out of the case and see if you can be heard OK on a call

If not or it still doesn’t work when not in a case try using the earphones with the microphone attachment plugged into the phone’s earphone socket when making or receiving a call to check if you can be heard OK.

Alternatively use the phone in “loudspeaker mode” and check.

If you can be heard OK when using either of these two methods then there is a problem with the phone’s internal microphone or perhaps the voice inlet hole on the bottom edge of the phone is blocked with lint or other debris.

To eliminate a blocked voice inlet hole as a possibility, try using a vacuum cleaner to suck out any obstructions and see if this clears it. Do not use a pin or probe to try and clear it as you may damage the microphone which is behind the inlet hole.

If it still doesn’t work after this then the phone will have to be opened and further tested to find the cause of the problem. It may be a faulty microphone for example.
