I use vMixCall to make a video call from my iPhone 6 to vMix on PC. On my mobile phone I see 2 windows. 1 little window shows the video from the camera of my mobile phone and the big window shows the video which will be send. This is ecaxtly the video which I can see on my PC too. I noticed that the fps from this big video on my phone is not stable. fps are changing. Does those changing fps come from the hardware from the phone, or from the browser, or why are the fps from the videos on the screen from my mobile pho
ne different? Should I try Android phone?

Thanks a lot for your answer.
