Good day Mike and Candy Barry!
Based on what you shared, you were previously able to use Link to Windows on your Samsung Galaxy A02s, but you’re now seeing a message that the app won’t work on your device, and it no longer appears in the list of installed apps on your phone.
I understand how confusing and frustrating this can be especially since Link to Windows worked on your phone before. However, this behavior is expected and related to a device‑level support change, rather than an issue with your Windows 11 Home PC or your setup.
According to Microsoft’s current Supported devices for Phone Link experiences policy, the Samsung Galaxy A02s is no longer included in the supported device list. As a result, the app may now be marked as incompatible in Google Play and, following recent system updates, may no longer appear on the phone.
Unfortunately, if the device is no longer supported, Link to Windows cannot be reinstalled or re‑enabled on the Galaxy A02s. As an alternative, you can try using web‑based options such as messaging or cloud photo access (for example, using your phone’s web services or syncing photos via OneDrive or Google Photos).
I know this isn’t the answer you were hoping for, but I hope it helps clarify the situation and saves you time from trying additional methods that may not resolve it.
Thank you so much for your patience!
Warm regards.
