Sony Xperia Z3 Compact - Screen detaching

I have 2 Sony Xperia Z3 Compact. On both of them the screen is detaching. The first one was already 3 times and is now with Vodacom repair centre (Job number ***5). It was sent by Vodacom to Sony. This phone was used by my Son.<br> The other phone screen just started to separate from the phone last week. This phone was in use by myself and have the exact problem. I have logged a complained with Sony mobile (ref no ***).<br> The second phone was supp**** by MTN.<br> <br> I cannot understand how come 2 Z3 compacts from two different ISP's have the exact same problem.<br> I was told that I will have to take the second phone to MTN repair centre.<br> I think that the phone should get to Sony Mobile directly.<br> <br> It looks like Sony have a problem with both front and back screen lifting.
