Excerpt: When Sony Service is patetic, why you want to go for expensive handsets, even sony handsets are made in China, If you give it for Service, then Sony will provide you refurbished handset, that means you are paying good amount of money for 2nd hand Mobile
which ultmately renders it useless. Thank u sony for an incredibly not so ...

Summary: Not only isn't the wifi not working in most cases (known Problem, without a solution until this day: http://talk.sonymobile.com/t5/Xperia-Z1-Z1s/xperia-z1-wifi-issue/td-p/388421/page/1), nope the display is another joke on its own. Used to be excited regarding the the speed of the phone and the quality of the camera.
Summary: Do not get this if going to use it with T-mobile. T-mobile it would never download images, etc. or get reception like it should and we thought it was just the phone. Got the Z1S after broke the screen (and the screens for the European version are next to impossible to find for repair shops) and had zero of the things that I didn't even realize were problems with the phone / not with T-mobile
