[Q] Audio Jack keeps detecting headphones

[Dwurck]

A week ago I updated my Xperia Z (6603) to lollipop from android 4.2.2. After this update every seemed to work well except for the speaker that all of a sudden didn't work anymore. At first I feared a hardware fault but then i noticed a notification from Smart Connect saying that the headphones where connected except they weren't. This explained a lot since the phone was indeed acting as is there were headphones connected. After this discovery I tried a lot of solutions I found on the internet.

1. I tried to plug in and plug out my headphones.
2. I rebooted the device.
3. I downloaded the app Sound About, it worked but it would mean that I will forever need to change the setting in the app if I wanted to listen to music on my headphones or over the speakers.
4. I fiddled in the headphone jack with a toothpick (??)
5. I reflashed the Lollipop firmware and tried different regions.

After that I tried reflashing every Sony Firmware that I found on the internet. I found out that when I reflashed to the first Android 4.1 Firmware that my speakers started working again. Giving me hope that this was indeed a Software problem and not a Hardware failure (since my warranty has ran out this March). After that I flashed Android 4.2.2 and everything was still all right. But then when I flashed to android 4.3 and it resulted in my original problem. And the same with Android 4.4.4 and ofcourse 5.0.

After I week I'm getting quite desperate since I now need to carry my headphones around for if someone calls me. Another problem is that I can't downgrade to 4.2.2 since last week I also bought an Android Wear device and I need at least 4.3 to be able to use it. So I was hoping that maybe some of you guys know if this is a commonly known problem. So if you are familiar with this problem and are able to help please post your solution below. I'd be extremely greatfull!

edit: To be more precise, it all goes goes wrong with Firmware 10.4.1.B.0.101.

I have updated my firmware to 5.0.2 about 5 days ago. It all goes fine until now, not experiencing any of your problem eventhough with KitKat Firmware 10.5.1.A.0.230 or Jellybean 10.4.1.B.0.101.
FYI because I've unlocked my bootloader and can't received OTA or PC companion update, so I download and flash the FTF using Sony Flash Tools.
Have you tried C6603_10.6.1.A.0.454_HK.ftf version? It works just fine for me.
And let me know whether your bootloader unlocked or locked.

==================================================================
Device = Xperia Z C6602
Firmware = Lolipop 10.6.A.0.454
Bootloader = Unlocked
Rooted = Yes

Thanks for the reply, I did try that firmware but sadly it didn't work for me. And my bootloader is still locked. Does that matter? It also tried updating OTA or Sony's PC Companion but both with similar results.

Since your bootloader still locked, unlocking it will lost your TA partition (can't use bravia engine on album). I've lost it because I don't backup the TA. So, if you plan for unlocking it, be sure backup your TA.
Don't know what to say, because Mine work just fine. But I believe that was Software fault because you've said that just fine on earlier Firmware and THE MOST IMPORTANT it's work with Sound About. Glad you still can use your Speaker although kinda annoying for keep changing the setting to swap between speaker and headset. I'll try to work around to find any way out for your problem.

I´ve got same problem, so I think must be a software bug, or something like that

A headset contains microphone but a headphone doesnt.
just insert the headset but dont pust it hard leave a little space. If you see headphone icon and not headset icon play any music. When music is currently playing and you hear sound on the headset just push the jack hard to lock. The headphone icon must still be a headphone icon. If it change to headset(thats the icon with microphone) icon repeat the process....if you insert jack on phone directly and push hard to lock , you will see a headset icon, in this setting you can never hear music.
