This is not good news. 

The new Microsoft Lumia 950 XL has been removed from sale by Carphone Warehouse. The standard 950 is not impacted. 

This information was confirmed to myself by a Microsoft representative within Carphone Warehouse.  

I was told the 950 XL needed a new firmware before going back on sale. Currently it’s only pre order now with a due date of 19th January 2016. 

This makes me wonder if it’s trouble again with the snapdragon 810 processor. Or maybe not its current firmware there were too many returns so Carphonewarehouse is waiting to sell stock once a newer firmware is ready. 

Either way this is not a good start for the new phone.
