I have been facing a strange problem with my Nokia 5800 while taking calls ..
The volume keeps dropping and suddenly its back to normal..
The Earpiece which seems to be responsible
This chip which is behind the front panel of the phone seems to have a problem .
We warn you that the following was done by trained technicians and if you attempt to do the same .. be prepared to loose your warranty ..
We opened up the front panel in order to find the ear piece chip ..
