To find a fantastic smartphone that suitable for us is not easy. Microsoft Lumia 950XL is that can be selected for the one of the dream phone that we should have. Although Windows 10 mobile is still in Technical Preview status, the system is worthwhile to try when the 950XL's function and user experience is continuous improvement.
I do not mind there are bugs with the New Windows 10 mobile OS (e.g. UI experience of Win10 mobile, speed for opening apps, numbers of UWP apps, etc), I only knew MS will bug fix all of them to improve the ecology of Windows 10. In additions, the updates sequence is more frequently than the other Smart Phone OS.
Apart from the more OS and firmware updatable feature, the security is also better than the other phone OS. The Windows 10 mobile is a safety system that can cut off the virus that affect the using of smartphone. That is another reason that I need a phone that like Lumia 950XL!
The power hardware specifications and the great photography effect are another reasons that I want to use Lumia 950XL.
Of course, the numbers of apps is not enough for 950Xl now. But when the RTM of windows 10 mobile is ready, the developers are willing to write more apps(include UWP apps) because the Windows 10 OS is so popular in the future moment(second only to Windows 7 OS)!
Being a Windows Fans, I must own a windows 10 mobile 950XL to support it!!!
