I have had Phone link working for years with my Samsung Galaxy S22 ultra.
Recently, part of the functionality stopped working, specifically, the "open phone screen" part. I keep getting an error 256.
The phone is on Wifi, connected to a Ubiquiti NanoHD.
The PC is a desktop on 10 Gbps ethernet.
Both are in the same /24 subnet, using DHCP with IP reservations in the router.
The phone says it's connected to the PC. The PC says the phone is connected to it.
I can see the phone's text messages & photos on the PC.
I just can't open the phone screen on my PC, or show any app on my PC's screen.

Yes, they are both connected via Wifi.
Phone Link/Link to windows has a setting to only connect through Wifi.
I don't see that setting in Samsung flow. But it works fine with the phone in airplane mode (cell disabled, Wifi on).
I have not noticed a performance/lag difference between the two apps. The screen sharing is snappy in both.
i agree with this but for some reason phone link lags a bit when Im using the mirror screen mode in the past, this goes away with samsung flow even though both are supposedly connected via wifi? I heard that the phone link app not working properly had to do with some "windows app" being discontinued? I could be wrong but I still cant believe microsoft hasn't address this issue.
Thank you all for reporting this issue. We are currently investigating this and will get back to you as soon as we have something to share. Thank you for your patience.
Samsung flow is good, but the functionality is somewhat different. You need to manually start it on both sides. You can only open a single phone screen on the PC side - not multiple windows for each app. There is no separate handling for text messages or photos in Flow, also.
The good news is that you can use both Phone link and flow at the same time, until Microsoft and/or Samsung fix the situation with phone screen not working in Phone link. When they do, I'll stop using Flow.
same issue same phone same pc operating system
