When I select on smart connect to start playing music automatically when I plug in the headphones, I face some problems. Note that the headphones I use are the ones included in the Z1 package. Firtsly, sometimes, even they are firmly plugged in, they are not recognized by the jack and the music is played by the phone external speaker. Also, when I don't have the headphones plugged in the software ''thinks'' that I have them plugged in, so it starts playing music. But, because I don't have them plugged in, the music isbeing played loudly by the speaker. Is this a hardware problem or a problem of smart connect? I think it's a hardware problem, because of the first aspect that I stated. Any ideas on how I can solve it? Thanks in advance.
