Samsung SCH-M828C cant hear any sound /music /ringtonson on speaker or even if u plug in headphones, what can i do?

Maybe try plugging headphones into it. That will tell you if the sound is dead or not. Also, on a lot of devices, there is a speaker kill switch integrated into the headphone jack that may be dirty or just need to be moved a few times with your headphone plug. However, if the caller can't hear you, it may be the audio circuit of the phone has gone to be with other Samsungs in the sky.

In order to check your mobiles capability to modulate sound just put your headphone. If you are able to hear the speech through headphone then the problem is with your speaker. If unable to get the speech the problem is with main pcb itself and to repair that you will have to go to service center it will be costly but if you are able to hear through headphone then it will be cheap.

did you try pressing the up and down buttons on your right when the phone is facing you?

Throw your phone against the wall and buy a new one.

Yea it sounds like the headphone have a sync problem. what you can do i go the Apple store and they should help you out they will swap your headphones and then it should work.
Thank you, Apple Care Technical Support

Yes the problem is coming from the speakers , so take the phone to a repair center and have them replace the speakers for you.

I think you just plugged an over size headphone jack...


OK, play music and try to plug and unplug several times.

if sound heard form phone just leave.

otherwise get replaced the headphone socket.
