Lumia 950 XL is an excellent specs. The 20MP camera does a fabulous job. The design is good but not impressive.
The OS sometimes seems to be laggy and would be fixed with the future updates of Windows 10 Mobile. Continuum is superb.
Got the display dock for free and Continuum works very well. Gaming is also very good on this device. I don’t see much lag on this device. I really enjoy using this phone.
