Headphone always on / detected

Hi there,

I have a question regarding the Sony Xperia Z.

The Xperia Z seems to always notify me that it has a headphone connected while it has nothing in there.

The little flap/cover is broken off from the frame, wich is something i have to mention, so it does notify about the phone not being waterproof.

When i use SoundAbout and rearrange the sound output i can call and hear everything just fine. When i disable the app, i have to use the headphones with mic to be able to call or the phone will not use the earspeaker or bottom mic.

What i wonder is, even after a complete factory reset aswell as disconnecting the headphone jack from the motherboard, the phone still notifies about the headphones being plugged in when the phone boots into android.

What i would like to know is, can this be a motherboard sensor failure, or does this have to do with the fact that the flap is broken off too?

What i tried:

  • Factory Reset.
  • Jack unplugged on motherboard.
  • Playing music while having the jack plugged and then unplug while playing.
  • Force stop "Smart Connect", cleaning cache and data.

I cannot seem to find what the cause is, im beginning to think that either some circuit is messed up on the motherboard itself or that the flap/cover is the cause.

I hope somebody can help me out here.

Thanks in advance.

I cannot believe this actually worked. Been a couple of years mine's been in a drawer with this issue, and the radio setting was the culprit. Had to uninstall Soundabout to get it back to normal.

It's not caused by broken off cover flap and the cover flap can be repalced by http://www.witrigs.com/replacement-parts...

As for the headphone, have you tired change a pair of headphones? And before you repairing the motherboard, what other you can try is replace the headphone jack.

I too have the same problem with my Xperia zr. I am not even able to make Soundabout work because even if I choose speakers in that app, music still plays only on the headphone. I can make calls only by connecting headphones or by talking on the loudspeaker. How to deal with the problem?

Soundabout helped me in this case. I to had the same problem. Guess it's the prob with the hardware. The audio is automatically routed to headphones.

The early generations of Sonys Xperia Z line, Z and Z1 have extremely unreliable headphone connectors. During my time as a professional service technician this was one of the most common problems on these phones. You will have to replace the headphone connector.

The repair is quite hard if you have not worked with a hot air gun before. If you know your way around one, it is quite easy as the phone is very modular and comes apart easy once you have removed the back cover.
