speaker microphone working if bending nexus 5

Hi guys,

i'm experiencing a strange issue with my nexus 5, basically the mic and the speakers are not working until i bend or apply a torsion to it. Look like there is a flab cable non properly connect something, i tried to open it but nothing looks "disconnected" .

I was wandering if some one had the same issue and if substitute the

[producto vinculado inexistente o deshabilitado: IF293-000] could solve that.

Thanks
