I was very pleased and also accepted that Sony is a media company and therefore something to have on the other hand seems to audio and video files just like that can play on the map. This requires a PC software names Companinion, and for that you need a Windows computer, no Linux version available! Already plenty bizar. I especially liked the camera and probably the best radio that I have ever experienced in smartphones. But then that went wrong with the independent boats. And then the unit 2 seconds to boot after the startup screen appears. So after asking substitute offered. Result: None available !? I had the phone to "repair" (glued housing when T!) Sending. Got it back after 5 weeks. With the same mistakes. Unusable. These devices just want too much at once.
