Microsoft recently broke the Windows 10 Mobile development from the main Redstone 3/4 branch. Since then, Windows 10 Mobile is no longer getting any new features. Although Microsoft did launch some features for the mobile platform, however, the new features re enterprise focused and have nothing to do with normal users.
It has been months since Microsoft is testing the Fall Creators Update for Windows 10 PCs while on the other hand Windows 10 Mobile is technically not getting the major update. However, still, Windows 10 Mobile feature2 update will bring over 70 bug fixes and some improvements like portrait mode in Continuum.
Things are now going to change after the release of Fall Creators Update. Windows 10 Mobile will be soon phased out but it will be supported by Microsoft until the end of 2019. It appears that things may soon become a bit complicated for the Windows Phone users.
As spotted by an Italian website, Microsoft is no longer updating the first apps for Windows 10 Mobile. Apps such as Photos, Camera, Calculator, Groove Music, Films & Videos, Voice Recorder are no longer being updated for mobile. For example, Microsoft compiled the latest version 2017.39081.14120.0 of Photos app back in June for Windows 10 Mobile. On the other hand, Microsoft is updating the Photos app for Windows 10 PCs every month with new features such as Story Remix.
Microsoft is also not compiling the apps such as Voice Recorder for Windows 10 Mobile. You can install any latest update for the first-party app on Windows 10 PC with Build 15063 but the same app version cannot be installed on Windows 10 Mobile Build 15063 as Microsoft has stopped the development.
Microsoft is now updating all apps for PCs as the Fall Creators Update is releasing next month. On the other hand, Windows 10 Mobile is not receiving the new first-party app updates and this trend is going to continue even after Redstone 4 release. Although Microsoft has promised that they will continue to support Windows 10 Mobile, it remains to be seen how well Microsoft will handle the existing phones.
