Microsoft has put a support site online with the message that Windows 10 Mobile is eligible for the Windows 10 April 2018 Update. It is not known which Windows Phones can receive the update.
There is a link to the page with more information, but it has not been updated and only mentions which devices the Creators- Fall Creators- update. Attempts by Softpedia to bring the update with a Lumia 950 XL, HP Elite X3 and an Alcatel IDOL 4S failed for the time being.
That the page for the Windows 10 Mobile April Update is striking. Microsoft announced at the beginning of this year that it no longer worked on Insider Builds for Windows 10 Mobile and last October it became clear that the company is no longer working on new functionality for the OS . According to Windows Latest who discovered the page, it could be a mistake.
