Ear piece problem.

If the volume is really low in the ear piece when talking on it, I've read where you can blow extremely hard into the earpiece. Over time the speaker will sometimes invert, causing it to perform terrible. A few hard blows in the earpiece can set the speaker back to normal. Hope this helps

If the volume is kep high and there is no dirt accumulation on the earpiece then it is possible that the earpiece speaker is faulty.
You will need to check if the spare is available with the dealer.

First of all clean the pores of the earpiece just in case there is block on the passage of sound fromt he earpiece speaker.
If this wont improve then the speaker must be changed after confirmation with a new one.

Hello,

try to increase the earpiece volume of your phone and if that does not solve the problem, you will have to change your earpiece.

The earpiece needs replacement, once its replaced, you would be able to hear loud and clear.

You can also use hands free (ear phone) for your phone till you find time to change the ear piece.

Take care.

check around the ear piece, make sure that rubber piece is there and properly placed around the ear piece.
regards

try to change a new ear piece to make a good out of voice from your caller....

Hello,

for the low volume, the fault is from the earpiece. Trust me, I faced this same problem and when I changed the ear piece, I began to hear calls clearly.

You could also get a earphone and use it to receive and make call pending the time you get the earpiece fixed. Earphone will even be much louder.

Concerning the flash, do some adjustment settings as you rightly suggested.

I wish you the best.

i think it's a software issue ..
i suggest that you should flash another software on it..

Seems your ear speaker has a problem. It need to be changed.

Have you raised the volume while you are on a call as this is the only way the ear piece volume increases.
If this doesn't work then I'm affraid you have a faulty earpiece
