Samsung alias earpiece speaker

Maybe your phone has fallen down once or twice before, this may have caused the earpiece and the mouth piece to have dislocated from their position. what you have to do is unscrew your phone and refixed the earpiece and the mouthpiece or you can give it to any phone engineer around you if you cannot do it your self.

the problem of your phone is in the earpiece.... try to open or dismantle your phone if you know how to dismantle... get a tester to check if your earpiece is still working.. and if not, u need to replace your earpiece... but if still working, try to clean the earpiece terminal maybe it is just corroded or dirty... goodluck my friend....

Go to Bluetooth settings and turn on Bluetooth.
The paired devices will be shown.
Delete paired device or unpair device .
This should solve the issue .

Since the mobile is paired with the Bluetooth speaker every time a call comes in the phone automatically connects to the Bluetooth speaker.

Switching off the Bluetooth speaker may also work.

The speaker phone and music uses a different speaker. You have a bad earpiece or connections to the main board via the gold plated fingers. This is a simple repair done by any shop. They should have used ones from dead phones laying around and charge you for the labor. If you are mechanically inclined, go to Howard's Forum and enter your question for description and photos on how to disassemble your model. You will need a T-6 Torx screwdriver.

please check the internel setting

Turn up the volumes on Ear piece -during- a call (on the side of the phone <===>) and on the speaker at any time. The joy stick does it I think.
