Which operator?</P><P>It may be software related (you may try to repair firmware altough it will wipe phone memory so copy them first). If it doesn't help you should contact Xperia Care and service center.</P> Tue, 07 Oct 2014 09:45:55 GMT https://community.sony.si/t5/xperia-archive/screen-problem-with-z1/m-p/3302120#M433804 SergioPL1 2014-10-07T09:45:55Z
