I thought Xperia z1 is best has sony made ever in every department but it's not. I'm very disappointed with sony's neglected response. I contacted sony 2 times but there is no response. also in support forum can't to get response sometimes. I agree with it is a best camera, yep in day light it's a best but in low light it's worse. z1 can't beat even Xperia c mid range phone. then why sony called z1 is a flagship. on white paper everything is good but practicaly it's not. I don't know what is the in z1 series. it freezes and screen getting black after that even restart button also didn't work sometimes,, 2) network issue 3) lowlight photography is worse compare to other high end smartphones.
performance is good but need new software update for optimisation.. I was very happy when I bought but now I'm dossapointed with sony neglect response. battery drains very fast also.
