It has worked on my HP Omen laptop successfully with an Alcatel a30 Plus, Samsung Galaxy S7 Active, and a Samsung Galaxy Note 8. The two Samsungs were relatively stable. The Alcatel was not.
Often, a Windows Update will kill this feature until the next update. That's the most frustrating thing about this service. It seems like it's just an afterthought to Microsoft; not really important to them.
I like being able to text from my HP Omen laptop and just hope that Microsoft puts some time into this capability. It would be better not to even have the texting feature if it is not stable. Raises my blood pressure when it doesn't work.
With my Mac, I just send the text and never have to worry. With my Windows 10 PC, I have to check each time, to make sure the computer is still connected to the phone. Often it requires a "Refresh" to make it work.
C'mon Microsoft. You want to make this work!
