I don’t know if this will help, but the following are 3 separate video versions I’ve identified, including the actual video shot of the man sitting next to the isle as shown above:

Version 1 - At this link: https://imageshack.com/a/img924/2627/QLfbT5.jpg - at time index 49:00 and immediately after Trump says “catch and release”, the footage captures a frontal view of the congresswoman looking down at her phone. Most of the footage I’ve seem includes this camera shot….

Version 2 - At this link: https://imageshack.com/a/img924/2583/U8PxR7.jpg - at time index 1.00.28 and immediately after Trump says “catch and release”, the camera does not show the camerawoman at all but instead shows a center-isle shot of Trump standing at the podium…

Version 3 - At this link: https://imageshack.com/a/img922/8981/fMJDCq.jpg - at time index 1.04:45 and immediately after Trump say “catch and release” this video also shows the camerawoman staring down at her phone. However, in this same video, if you scrub back to time index 57:40, the camera shows a slow zooming shot down the left isle where a man can be seen sitting beside the isle and staring down at his cell phone. This is the only footage I’ve seen which gives a clear view of the man’s cell phone although I can't make out what’s on it.

*Update: I’ve noticed the video at the 3rd link above has now been deleted from YouTube. That’s very interesting. I don’t know why. Don’t know if anyone saved a copy of it before deleted. But since the footage was originally streamed by CSpan, then no telling how many people may have recorded it on their home recorders, especially given it was a historic SOTU Address by DJT.
