SPEAKER ISSUE FIXED !

It could be a speaker issue. Try using you phone on speaker phone, or ear buds with with built in MIC or blue tooth headset. If it works with these options then its an issue with the speaker. If it doesnt work even with other options then its a more serious issue

I just dealt with one of these last month, its a ten minute fix if you have a soldering iron. The wire gets strained inside, they didn't allow enough slack in the wire for the movement of the earpieces. A quick resolder of the broken connection and a dab of hot glue to keep it from moving was all it took. Cost of repair was zero.

Hi....Just check the sound with stereo headset.If it is working properly ,right speaker has to be replaced.If the situation persist same before,you may have to check the motherboard .

You need to go to samsung shop .. You need to replaced new speaker on your phone

you need to replace the left front door speaker

Your earpiece mechanism is bad & needs to be replaced.

I have fixed numerous phones like that, even my brother has the same issue before.

go to a local repair shop to have it replaced.

pushing the jack hard may result in some connections pushed way off, and there is no contact to the speaker. Please see the nearest technician.

Same issue showed up for me today very randomly...

HD comes on and off for no reason and sound cuts in and out. This fix worked for me:

1.Disconnect the left speaker from the sub woofer.
2.Take the 4 screws out on the bottom of the left speaker. (They are under the rubber matting you can just poke holes through it)
3. Remove the bottom plastic assembly from the speaker
4. Cut the 4 wires to the headset chip. Careful not to cut any others to the speakers themselves!
5. Unscrew and remove headset plug chip
6. Reassemble and plug left speaker back into sub woofer.

No more HD issues =)

i fixed this problem

The phone came with a headset. Plug the headset in and out a few times; it should reset the headset icon and phone can be used regularly again

i encountered this problem after i started using a bluetooth headset. when the headset is not in use (not turned on, not even with me), sometimes there is no sound from the speaker, and the other party cannot hear me. meanwhile, the call timer is clicking away indicating the call connected. it seemed there was some issue in the bluetooth stack, and the phone thought it should be communicating with the BT device rather than it's onboard speaker/mic. to resolve, i disconnect the call, go to the main screen; in the bottom right corner, use the bluetooth manager icon to turn BT On then Off again. this resets the phone's speaker/mic usage, and calls can be made like normal. i hope this helps you.
