“Windows 10 Mobile, version 1709 (released October 2017) is the last release of Windows 10 Mobile and Microsoft will end support on December 10, 2019,” reads the Microsoft support note. Further, smartphones running Windows 10 Mobile version 1703, such as Lumia 640 and 640 XL, will only be supported till June 11th, 2019. Moreover, in the support note, the Redmond giant also recommends Windows 10 Mobile users to shift to iOS or Android devices. “With the Windows 10 Mobile OS end of support, we recommend that customers move to a supported Android or iOS device. Microsoft’s mission statement to empower every person and every organization on the planet to achieve more compels us to support our Mobile apps on those platforms and devices.” It should be noted that Microsoft had stopped developing new features or hardware for Windows 10 Mobile since 2017. Although the company continued to provide security and software updates to Windows 10 Mobile devices, this too would now cease from December 10th, 2019, and devices will be no longer be supported after this date. However, the company might continue supporting third parties or paid support programs for the platform for a later date. Once the device reaches the end of support, some of the features will slowly stop working. Microsoft notes, “After the end of support, automatic or manual creation of new device backups for settings and some applications will continue for 3 months, ending March 10, 2020. Some services including photo uploads and restoring a device from an existing device backup may continue to work for up to another 12 months from the end of support.” Microsoft also stated that it will also be phasing out its built-in backup tool after the support ends. Hence, the company is encouraging its users to manually create a backup before December 10, 2019. To do so, the users can go to the Settings -> Update & security -> Backup -> More Options and then tap Back up now before that date.
