I am facing an issue in my app as when I start recording through camera it tilts to landscape which is not the requirement. The requirement is Recording should start according the the orientation of the Device. Means if device is in portrait mode then recording should start in Portrait and If camera in landscape mode then recording will atart in landscape.
But in our case when we click on start recording button then camera orientation will automaticaly changed to Landscape but Device still with the portrait orientation.
So, Please suggest any solution regarding that.

I had the same problem and this little snipped fixed it
I am not sure why it doesn’t start at the current phone orientation but I am sure this fixes it.
