i would return it and get a new one ive never heard of this problem

 

I just got a new GS2 and the handset speaker does not work at all. The loudspeaker and earphones work without a problem. How can you tell that its the Headphone jack sensor causing the problems?

 

Hi there,

Your experience with your GS2 is exactly the same as mine with my brand new Galaxy Note!
Mine is now sent back, so gone is my new gadget I was so eager to get as soon as possible...

I always had HTC's, this was my first Samsung... and now probably will be my last too!

Regards,

 

Errrmmm . i just had that problem and restarted the phone . now its working again i think some app may be the cause .

 

I had the exact same issue. I had dropped my new phone in the snow but it was cold enough it did not get very wet.

I dried my phone off and tested it out, and had the issue you described. (No Audio / No Mic) - as if a headset was plugged in.

I thought the Mic had been damaged so I spent some time drying it to no avail. I then came on here and researched and found your thread.

I decided it was probably the 3.5 jack causing the issue so I lightly heated with a hair-blower on "warm" setting. For a couple minutes careful not to heat the screen or get it too hot, then I sprayed a compressed air "dust-off" can into the 3.5 jack from about a foot away.

Turned the phone back on and everything is functioning great.

Thanks alot for turning me in that direction, if I hadn't acted fast I bet there would have been damage.

Hopefully this might help someone who get's their phone wet, or snowy as well.

 

Same thing happened to my note; just reset it and for me my it was low on battery so i plugged it in and voila, worked right away. Hopefully that save's someone from getting stuck with a bunk loner phone.
