I couldn't use this function so I email to Sony, after few weeks of waiting they finally replied with... "We apologize for any inconvenience caused.
On the screen mirroring. For the screen mirroring it was due to the new update having error on the application. We have already send your request to our development team regarding this issue, Kindly wait for the new update for the resolve of the issue"
So it's due to hardware or software issue ?
