Possible corrective measures
If you use any protection tape or case,
check to see if it has covered the area
around the proximity sensor. Make sure
that the area around the proximity sensor
is clean.
Check the settings status of the sound
menu to make sure you are not in vibrate
or silent mode.
Remove the battery, insert it again and
switch on the phone.
