Headphones mode stuck

[Crary]

Hello! So I have Sony Xperia S on Android 4.1.2 and from yesterday till now, my phone is stuck on headphones mode even if the headphones are not plugged into the phone. I tried restarting the phone, plugging the headphones on and off several times, but there is no effect. So should I look for professional help or there is somethink I can do to fix it? (I`m from Lom, Montana, Bulgaria.)

It also happens to my Xperia S. But I think it  to install another app to solve it when Sony must be awared about the problem...

I neve use that phone hole. I've installed soundabout for a while, but other things got ruined, like the speakerphone i n my calling, or whatsapp audio messages. Then I`ve unninstalled it, and everything got back to normal, including my headset settings...

But now, the problem has began again! I am not using the phone and the icon keeps showing up. I didn`t want to buy another cellphone now, cause its a little bit expensive here... I just want it to work propperly..

I have same problem here. Couldnt fix even after pc companion repair and restarting several times rather I lost my important files. I did factory restore too. What's with Sony phones?
