Xperia Z Doesn't Recognize That Earphones are Unplugged

[yussssus]

My issue started when I was using the earphones and received a call on Viber. This happens a lot but this time it's not being fixed. After that, I cannot hear anything through the ear speaker, not all apps notifications can be heard through the loudspeaker: in example: sms yes Gmail yes whatsapp no Viber no.
Music is not played through the loudspeaker. Calls are only heard through loudspeaker. Earphones work always. Seems that the phone is confused and thinks that the earphones are still plugged. I reinstalled. The phone software through PC companion repair, still the same. Appreciate. Some thoughts from the xperia staff. Thanks.
Xperia Z C6602
Android 4.3

When you reinstalled the firmware, did you restore a backup of the applications etc?

No, it was a clean format, did not restore anything, even contacts. I can confirm now the problem is that the phone is not detecting that the earphones are unplugged. I noticed that since the FM radio app works without anything plugged, just gives static noise when plating through the loudspeaker.

So, any updates??

Sorry for the late reply. Please check if there is anything in the headphone jack such as dust etc. If there is not then please try this : Main Menu > Settings > Apps > Smart Connect > Clear Data. if you still have no luck then you will need to speak directly with your local  Xperia Care team so that a repair may be arranged.

What EXACTLY did you use as earphones?

i suspect whatever you used damaged the circuitry responsible for auto-sensing accessories plugged in the headphone plug.

Thanks for the reply. I tried your solutions but didn't work. I will take it to the service center. Wanted to avoid that since I'm using it non-stop.

I use three headphones on it:

1- Xperia Z provided earphones

2- Bose On-Ear headphones

3- Nissan Murano's car aux audio

What do you think? Maybe the car aux can damage it?

To be honest this is only one of a number of possibilities, however if any force was applied to the headset whilst it was connected to the phone this could lead to damaging the headphone jack.

Took the phone to local Sony maintenance, the headphone jack was damaged as stated. Had to replace to headphone jack for 40$ and the phone is no longer waterproof.

To tell you the truth, i prefer my Xperia Z as non-waterproof. The sound volume on the loundspeaker is WAY BETTER now.
