How can i increase volume for mic iphone 3gs or input volume during calls..they cant hear me clearly..thats my phone problem..iphone 3gs..
Hello
1 .You need to confirm if its the volume or the mic of your phone that has the problem.
2 .If its the mic,your callers would not hear you but you would be able to hear them.
3. You can Adjust the volume of your iPhone by depressing the volume button on the left edge of the phone, close to the top. This will cause a volume indicator to appear, superimposed over the other icons on your screen. This will increase the volume of your ringer. If you wish to adjust the volume of the phone speaker, use this button during a live phone call. You can also control the volume of your speaker when you are using your iPhone as a music player in the same manner.
4. If its the mic,remove the iPhone from the case, as your case may be blocking the device's microphone.
5. Plug the iPhone device cable into the iPhone and into the computer's USB port.
6.Launch iTunes. Click "iPhone" or the device's name in the sidebar in iTunes and click "Summary then Click "Check for Update" and "Download and Install" to update your iPhone's OS.
7. Remove the device cable after the update finishes and insert your headphone jack into the iPhone's headphones port,tap "Phone" on the home screen, tap "Contacts" and tap a contact to place a call.
8. Press the "+" button on the microphone to increase your microphone's volume.
9. If the problem persists take your iPhone to your local Apple Store for professional service.
BEST OF LUCK
