This exclusive Galaxy Note 10 feature might come to older Samsung phone too

Samsung has introduced a new feature in the Galaxy Note 10 and Galaxy Note 10+ smartphones. Samsung has partnered with Microsoft to enable Windows Live. With this feature, the screen of the Note 10 automatically gets mirrored on any Windows 10 PC. Users can access messaging, notifications and other features of the phone on the PC itself. If you have touchscreen Windows 10 PC then you can control your Galaxy Note 10 from the PC itself with touch.
Interestingly, developers have discovered that this feature works for older Samsung phones running OneUI as well. To make this feature work in older Samsung phone, the user simply needs to sideload the “Link to Windows” APK. This APK is only for Samsung phones and other devices are not supported.
With support for older phones, all that Samsung needs to do is offer a software update for older devices to enable this feature. However, there is no official word from Samsung on that.
