Why was the Z3 I would like to briefly explain:
Samsung has just disappointed me in the last 2 years. The cheap processing, the bad update policy, to colorful menu, all the Samsung bloatware that is useless and you can not uninstall this also to root without his cell phone, came out of the question for me. Furthermore it has my niece a S5 and after less than a year this begins to lose on battery power, as well as bucking. These problems I had also with my S3 and I suspect that this is simply related to the Samsung UI.
LG G3 - and this I had several times in the hand to read and understand me so. Read Many reports and watched videos. Here the problem exists with the sensor of the camera. This is extremely hot and the color display in the UI did not like personally.
Now for the Z3 - the design and the display brightness (and I speak here of the automatic regulation) so far the best I've seen. Even when the sun is still all right to read. The colors appear natural and not very colorful. If you go to an electronics store and a cell phone look more closely, they are all converted to 99% on manually and the brightness is set to 100% just to the display good effect comes. It then provides this to Automatic, so you can clearly see the difference to the Z3
Haptics, speed (surfing, games, mails etc.) outstanding, no stuttering (or Micro stuttering) nothing, everything runs smoothly as it should be. In the three weeks I absolutely could not find anything negative in terms of performance and is determined not only by the 3GB RAM but also the absolutely clear UI from Sony. The menu is not overloaded and not littered with any unnecessary apps as with other manufacturers. The preinstalled apps from Sony I all still on it and use it, and if one or the other do not like the one app, so you can easily uninstall it without any problems - so it must be, because if you have that kind of money for a new smartphone picks it up, then you should also be able to decide what you want to have it or not.
Battery: There is not much to say except that you have to be afraid to mention how to load a mobile ;-) battery lasts 3 days without any problems through and that even though I several times a day mails views into Internet go, and from little to a Games and some photos do. For the Stamina mode, the battery ensures saving when the display is off. If one uses the Ultra Stamina mode, the battery lasts without the cell phone to charge 2 weeks.
Camera: when the light conditions match makes the camera work, even in the dark with flash photos come clear yet over. Only when the room lighting is insufficient because, a noise comes into the picture. But the verschmerzt you all through all options and partly funny gimmicks (additional apps for the camera you can free download from the Play Store) that Sony has built with. The more one is dealing with the camera, the more options and opportunities you discover. For my needs, the camera goes, anyway.
And now for the small differences that the phone still offers: if you have a PC, tablet or notebook with Win 8.1 has (in my case, the Surface Pro 3) and the mobile phone to the tablet coupled via Bluetooth, a call is automatically made so that you can use the connection from the Z3. The whole course encrypted.
Also a fine option is that you can store different WLAN networks as trust and the Z3 then automatically establishes the wireless connection when you are near these networks without the need to turn on the WLAN manually.
Miracast works impressively fast and without any lag in my S3 and the corresponding HUB Samsung also did not make it after 2 years and multiple updates, make a smooth connection between mobile phone and LCD. The Bluetooth connection to my car radio and Bluetooth speakers at home without disconnections. A dream compared to the S3 I owned the here I constantly had in the Bluetooth speakers disconnections.
The Small Apps are very useful to quickly calculate something in a new window or to look on the internet without the previous window to close fast times. Well, I also think that Sony offers free here some of these small apps in the Play Store.
After my initial fears whether it was the right decision for me to opt for the Z3 and invest a lot of money, I have to admit "YES" and I do not want to miss. At Samsung, I will definitely not return to the previously very good experience with Sony. Sometimes you have something to look over the edge to discover new or would like SONY say "It's not a trick. It's a Sony"
From me a strong buy recommendation with no restrictions!
