Z3 compact faulty mini jack

[Molorinko]

I bought my Z3 Compact a couple of months back and i absolutely love it! But i've recently been having a huge problem with the minijack port. It started about a month ago where i would lose the sound/ sound fading on one ear whenever i came near the plug, eventually the phone would no longer register that my headphones were plugged in. At first i thought it had to be my headphones, but after testing these with every gadget in the house and testing all my other headphones with the phone i realized that it was the phone that was faulty.

So i contacted my retailer and had them get the phone fixed. I was told that they changed the motherboard, and two weeks later i had it back fully working. Now, a week after i got it back, i'm experiencing the same problems once again... I can't really be this unlucky, is this a known problem? I read that other Z3 owners had been experiencing problems with the minijack port being "loose" and disconnecting their headphones?

Are you using correctly fitting headphones? however all you can do is either return your device to the place of purchase or contact Xperia care http://www.sonymobile.com/global-en/support/contact-us/

A mother board failure? wich week of production Is your phone?

@Thommo

I'm normally using Sennheiser CX 300 II, but the same problems occur when i plug in the Sony plugs that came with the phone. So i don't know...  And yeah, i should try contacting Xperia Care. I'd like to return the phone and get a new one if i could but i'm affraid they would have to send it to repair again.

@il_vecio

I'm not saying that it was a motherboard failure, but according to the service report, they did replace the motherboard. As for which week of production my phone is, i'm not sure. How do i check that? I bought it early in october though.

Dear Molorinko, please have a read to this topic , you'll find a post of mine in which i show how to get the week of production (by the way it's a label located under the SIM tray).

it seems that there Is a strange correlation between certains weeks of production and some known device failure

[Molorinko]

Okay, so i checked the phone and it says 14w37. So week 37?

You should contact Sony Xperia support. http://support.sonymobile.com/global-en/contactUs/ it sounds like you may just have wear and tear.

[il_vecio]

Yes, 37 Is the week of production, and as you can read in the other thread a lot of user have a 37/38 week device. As Phy did before, i suggest you to signal this correlation to Xperia support.

[Molorinko]

Yes, i will do that. Thank you!
