Hallo i have a problem With the earphone input. When i plug in an earphone The Phone does Not recognize It. It seems an hw problem But if i reboot The Phone the earphone works, if i unplug the earphone the Phone continues working as they are plugged in, mic is disabled and no sound from speakers, again when i reboot The Phone i can use it withouth earphone.
Another weird thing is, if plug in earphone and reboot, it works, once rebooted everytime i plug or unplug ep media player starts playing Music.

Phone has android stock 2.3.7 and it is Not rooted.
I tryed To install again and nothing changed.
Liveware manager settings are all off

Please help.

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?

If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.
