Good news: to my surprise in Wire secure messenger video calling suddenly works well on my XA2+ (Sailfish 4.1).
which version of Wire? thanks
Wire secure messenger 3.71.1000
Did you try the loudspeaker option or are using a headset?
Xperia 10 III, Sailfish OS 4.5.0.24: Wire messenger loudspeaker is not available in my setup.
Wire version currently on F-Droid 3.82.38
When the call is ongoing, I see no loudspeaker icon: the other end voice is in the ear speaker.
Update: I found the “Speaker” option in Wire.
When initiating a videocall in portret mode (landscape doesn’t respond) 3 option icons are available:
Microphone - Camera - Flip Camera
To get to the Speaker icon I turned off the Camera option and that also makes Flip Camera option disappear as well and Speaker icon the appears visible instead.
After setting desired Speaker option, re-enable Camera.
