In a somewhat surprising twist, Microsoft has added a new version of its Lumia 635 handset in some regions. Don’t get too excited though; it appears there’s only one change: A doubling of the phone’s system memory.was spotted by the AllAboutWindowsPhone blog
That doesn’t mean that phones with less RAM won’t see the Windows 10 upgrade. However, Microsoft’s Corporate VP, Operating Systems Group, Joe Belfiore has already said that the company is working to get Windows 10 on phones with 512MB of memory; they just may not have all of the new software features available to them. If you haven’t seen them yet, here’s an overview from the currently available early preview of Windows 10.
As much as I’d like to see Windows 10 arrive for the complete line of Lumia handsets, I can understand the challenge Microsoft faces with limited memory on low-cost phones. Unfortunately, the best selling Lumias have been the ones with 512MB of memory so the company will be challenged to get these handset owners on its new software which unifies the experience across phones, tablets and computers.
