File this under strange, but Microsoft appears to have accidentally revealed two new devices on its website, the Microsoft Lumia 640 and the Lumia 640 XL. The page has since then been pulled but WinBeta managed to grab a screenshot of it before it went offline.
While these handsets have obviously not been confirmed by Microsoft, it's quite possible we'll see the devices being unveiled at Microsoft's keynote in the Mobile World Congress 2015 tomorrow.
The devices will probably be entry-level as an Adduplex report earlier this month confirmed that we would probably see a Microsoft RM-1031, a phone with a 4" display with 480x800 resolution. The model number matches the Nokia XL, an Android phone that was short-lived, so Microsoft may soon be launching successors for the Nokia X and Nokia XL, which are likely the devices (un)announced above.
Still, without knowing the full specifications, price point, or an official confirmation from Microsoft, it's difficult to determine whether these phones will be the recycled versions of the previous Nokia handsets, but we'll let you know when they launch. Other low to mid-end Lumia devices are expected to be unveiled at Microsoft's keynote tomorrow, including the Lumia 1330.
