Xperia Z2 recognizes earphones connection after 6-8 seconds

[Alam1998]

I have xperia z2 running android 4.4.2 1 kitkat and I want to know if taking almost 6 seconds of time is a normal thing for my device to recognize earphones connection. things I did already that haven't helped: restarted the device, boot to safe (takes the same time durition), used different earbuds and headphones, wiped the headphone jack...
Any different suggestion from ones I mentioned above would be appreciated.

How about settings > apps > all > smartconnect > clear data > restart the phone

I did cleared smart connection cache and restarted the device, but it stills taking the same durition of time which is 6 seconds, same in safe mode.

I'm sorry to hear that, you might have to contact your Local support to get your device inspected.

I'm not sure if it's the default time for earphones recognition in all xperia z2 devices, I wonder...
anyway thanks for your help and soon reply.

It should be right away, @alexdon could you test this?

Just tested on my Z2, 2 seconds to recognize the headphones. But my Z2 has been recently reset (with PCC).

By a pc reset for my device, will that update the software? , because I don't want the device to get updated and it stills with 4.4.2 1 (the out of box android version).

The repair will install latest firmware available.
