How do I adjsut the earpiece volume on my Nokia 2680?

Try to make a call, and then press the up button during the call to increase the volume. Pressing the down button will reduce the volume.

From the Nokia 2680 manual:

"Loudspeaker
If available, you may select Loudsp. or Normal to use the loudspeaker or the earpiece of the phone during a call."

Does your phone definitely have speakerphone? It seems that it's an option, not standard on all of this model.

Have your earpiece retested on another device if you have. If issue occurs on another phone w/ the same earpiece, then you're gonna need to buy another earpiece and if the problem only occurs w/ your device then I suggest you do a master reset.

Make sure ther is nothing obstructing earpiece. Such as make up, dust, etc.

Check your phone's settings or you can adjust the volume while talking to someone by pressing the up to your keypad.

Hope this solution helps. Thank you for using Fixya

You have to be on a call to adjust the earpiece volume. Just call your voice mail and turn the volume up. It's the same button you use to turn the phone ring volume up and down. When you're not on a call the volume is for how loud your phone rings. When your on a call the volume buttons adjust the earpiece volume

First you change your cell phone speaker and then your volume problem will solved
THANKS

Some options are available in the phone itself.....

change the the ear piece

Your earpiece might have a problem. Normally the volume on the phone works with the earpiece
