New Windows 10 Mobile release hints at 6 October event reveal. And will Surface Pro 4 be there too?

Microsoft seems to be finally coming up with its next mobile ecosystem

Microsoft has today released the new preview build of its Windows 10 Mobile platform.

Build 10536, which is only available to Windows Insiders, has a number of significant features, with arguably the most important being ‘one-handed mode', which can be activated by pressing and holding the Start button.

Meanwhile, the mobile hotspot function has apparently been fixed, as has two-factor authentication for accounts, which now allows both text and on-phone authentication.

The photos app has been updated with better visual browsing of OneDrive and linked PC folders, as well as access to thumbnail folders that may lie on an SD card.

A reported endless loop displaying the word "Loading..." when the phone boots has also been fixed.

All in all, this build feels like Windows 10 mobile is now in a close-to-launchable state, which is timely, considering Microsoft is planning a New York-based media briefing on 6 October 2015 in New York.

Rumoured announcements are Lumia 950 and 950 XL handsets, and with the event promising "exciting news to share about Windows 10 devices", seems a safe bet that Windows 10 Mobile may debut on these devices.

Meanwhile, as well as a new Microsoft Band wearable - which is hardly worth discussing here - another device rumour just won't abate for this event: the Microsoft Surface Pro 4 is strongly expected to make an appearance.

After Apple's reveal last week of its iPad Pro, which many seemed to accept as an ‘innovation' on the iPhone company's part, it might be timely for Microsoft to pull out an even bigger gun in what may, overnight, have become an escalating hybrid tablet war.

If Microsoft has any sense, it will also be encouraging its partners to begin working on truly competitive productivity devices that follow a similar build style of thin, light tablets and tear-off keyboard covers.

As PC and laptop shipping figures continue to slip, the enterprise is now crying out to move beyond attempts to base productivity on simple tablet interaction alone.
