Microsoft pushes another nearly finished preview of Windows 10 April 2019 Update (build 18356) with minor improvements and updated Your Phone app with phone mirroring feature.

Microsoft is now making available Windows 10 build 18356 for PCs enrolled in the Fast ring of the Windows Insider Program. This is the preview number 31 releasing as part of the 19H1 development with several fixes and an updated version of the “Your phone” app experience.

Windows 10 build 18356, according to the company, addresses issues with Microsoft Edge, night light, inbox apps, and fixes problem that resulted on green screen of death with kernel security error.

In addition, Microsoft is also rolling out an updated version of the Your Phone app that allows you to mirror your Android phone screen directly onto your device without even unlocking your phone.

While in the experience, you can launch mobile apps and interact with your phone like you do normally. However, the touch input doesn’t work, and the mirror feature is only available for a select number of phones. Surface Go will be the first device to support this new feature.
