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 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, reinsert it and switch on
the phone.
Try to perform a software update via the
website.
