TL;DR – It is very good! The UX isn’t perfect, but it is getting there. I’ve never used a Microsoft Lumia 950 XL before. I ordered the 950 XL because my current 1520 has become a mostly unusable nightmare. Phantom touches galore made it one of the most frustrating UX I’ve ever had the terror of using. I understand it was the hardware. So I tried to keep an open mind. Based on Windows 10:AU’s performance on my 1520, I figured that the 950 XL couldn’t possibly be worse…could it?
