I had the exactly same problem , all of a sudden crack , a blong single crack appearing on the screen just out of the blue. Had a tuff time convincing the service center people regarding the same as they were not willing to beleive that the crack had come without any force/drop etc. then i had to show them the following link: https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCcQFjAA&url=http%3A%2F%2Fwww.xperiablog.net%2F2013%2F11%2F08%2Fsony-will-repair-certain-cracked-displays-for-xperia-z-series-suggests-leaked-info%2F&ei=TIgIU8W_L8mPrQenjoGgAg&usg=AFQjCNGX-bsSu-QFoqIbJ6gA64Wnv8zWiA&bvm=bv.61725948,d.bmk and make them understand that its not the customers fault here but a manufacturing defect . Though it took a month of support , taking a ticket and consulting support people at xperia care but i am happy that sony has valued its customer. I thought this was my last smartphone or gadget from sony , since the defect made me beleive that sony might have used poor materials , those not of high standard like gorilla. But finally after all this sony approved of a replacement . I thought i was loosing around Rs.28k for a use of a phone in just 4 months but thankfully sony didnt let the worse come. my phone didnt have any scratches/dents or any signs that could show it was manhandled , neither was it , i love my phone and all my gadgets. There was this one long crack on the screen and it was totally unusable since the screen couldnt be unlocked because of the crack. The screen of zr cant be replaced either as regular or service repairs and need service center support in case something happens. I would also like to thank the service center people at neosa asansol for understanding the problem and taking care of their customer. To Sony: Thank you, for your after sales support and please make sure you continue the same. I hope i wont have to deal with other manufacturing defects with sony products in the future , but if i do please continue extending ur excellent support after sales so customers come back to you. request: please release Kitkat for zr too. waiting for it.
