"Smartphone synchronization", which links Windows 10 and smartphones, is definitely improved

　According to Microsoft's blog, the Build 20185, which is distributed on the devchannel of Windows Insider Program (WIP), has improved the smartphone synchronization app (English name Your Phone App).According to the actual investigation, there are some changes (https://blogs.windows.com/windowsExperiences/2020/08/05/annnnouncing-Windows-10-Insider-PREVIEW-BUILD -20185/).

　One of them was simplified the smartphone registration method, using a QR code.The other is that the "smartphone screen" function has been enhanced, and it has become an "app" function that can directly launch the application on the smartphone side.

　The announcement on the blog was talked about in Dev Channel, but when I looked it up, the same function was confirmed in Windows 10 Ver.20H2 (Build 19042.432), which is being distributed in WIP Beta Channel.Given this, it seems that it will be available from updates this fall as soon as possible.

What is the "smartphone synchronous app" mounted on Windows 10?

　A smartphone synchronization app is an application that links Android, iOS smartphones and Windows 10 PCs.It is in Windows 10 as standard, but can be uninstalled or installed from the Microsoft store.

　As a function, you can display your smartphone photos, display notifications, send and receive SMS, and call.

The smartphone synchronization app includes "Photo" (display of photos in smartphones), "Notification" (display of smartphone notifications), "Message" (SMS transmission and reception), "Call" (PC is headset and can be called.There are four functions of), and for some Samsung terminals, the "smartphone screen" or "app" (20H2 or later) functions can be used.

　However, in order to actually use it, it is necessary to install a "smartphone synchronous management app" on the smartphone side.

To use a smartphone synchronization app, you need to install a "smartphone synchronous management app" on the smartphone side.

　It seems that the functions consisting of these two applications are called "Windows Link".Furthermore, the "smartphone screen" function that displays the smartphone screen on a PC only when combined with some models of the Samsung Galaxy series can be used (https://blogs.windows.com/windows Experience/2020/08/05/05/05/05/05/05/05/05/Microsoft-and-Samsung-expand-partnership- empowering-You-ACROSS-WORK-and-play/).

　Looking at the functions and how to use it, Windows Link seems to do not need to look at the smartphone while using Windows PC.In other words, telephone and SMS can be used without operating the smartphone side, and photos in the terminal can be handled from the PC.

　However, if you look at the connection method, it is assumed that you are at home and company.The connection between the smartphone and the PC can be used via the Internet, but on the smartphone side, only the wireless LAN is used by default.

　You can allow connections by mobile data communication by changing the settings, but the "smartphone screen" and "calling" function require the same network or Bluetooth connection.For example, an Android tethering function cannot be used because the connected client and the Android side cannot directly communicate (not the same network).Of course, there are many ways to connect with the same network even on the go, but it means that you can use your smartphone normally outside.

The registration method in the "smartphone synchronization app" has changed

　In the conventional Windows 10, when linked to a Microsoft account on a smartphone synchronous management app on the smartphone side, a smartphone was also registered on a PC.

　On the other hand, in Build 20185, the Windows 10 smartphone synchronization application displays the QR code, and the link process is completed by reading it with the smartphone -synchronous management application on the smartphone side.

Until now, if the smartphone synchronous management app was installed on the smartphone side and a Microsoft account was registered, it was registered on the PC side, but after 20H2, it became possible to register using the QR code.The connection is completed by reading the QR code displayed by the PC smartphone synchronization app with the smartphone synchronous management application.

　It has become much easier than entering a user account or password on the smartphone side.This mechanism is already supported by the current "Smartphone Synchronous Management App Ver.1.20071.95.0", but does not work on Windows 10 ver.2004 (20H1, May 2020 Update).Windows 10 ver.20H2 (the version notation will be changed from the next time, Build 19042), which is being distributed in WIP Beta Channel, will operate.Of course, DEV Channel's Build 20185 also works.
