The time has come to say goodbye to your Windows 10 Mobile device. Microsoft has stopped developing new features or hardware for Windows 10 Mobile back in 2017. Now, the company is ready to end support for security and software updates. Starting December 10, 2019, Microsoft will no longer issue these updates. The company is recommending its users to switch to Android or iOS. After it pulls support in December though, device backups for settings and some apps will continue to run for three more months until March 10, 2020. Microsoft also notes “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 end of support.”
