I have tested the above devices. Among them, devices 1, 2, and 3 can make video calls normally. Device 4 can also complete the call but still reports an error.
Device 5 shows a completely black screen on the call interface without any buttons, making it impossible to make a call at all.
The testing environments are as follows:
- Making calls to each other under the same Wi-Fi network.
- Device 1 uses a 5G network to make calls with other devices that are connected to a Wi-Fi network (home broadband).
It seems that even under the same Wi-Fi network, the connection setup takes a relatively long time (except for Device 2, which always establishes connections very quickly). It feels like it takes around 30 seconds, so there might be room for improvement.
It would be great to add the function of switching between the front and rear cameras. Overall, the video call function is amazing! Thank you so much to the developers!
