Ups, you're right. i couldn't beleve it but my screen is actually a bit loose. Black screen problem go away when pressing the screen back in place.
I would like to know how you performed the task with the glue. I am a bit affraid to use too much glue which might damage the inside of the screen.
I don't see your email anywhere...so i am not able to write you directly.

I too had the same issue. I had purchase Xperia C4 one day back and the phone screen goes black on every call. I have tried to update the system as well as reset the phone to factory setting but it not works. Now I am so tried and need not to know what to do with the phone as there is no solution found on the sony website or any other website.
please suggest if there is any solution on this.

I had the problem with black screen when started call and before put the phone to my ear and the problem was the screen protection plastic on brand new handset - I havent got the regular screen protector. When I took the plastic, off screen started to work. Before that I had to press twice the power button to wake up screen.
