Sometimes you can, but it depends on the camera.
1. Turn off camera flash
2. Adjust exposure to less than 1 refresh cycle (e.g. 1/150sec exposure
3. Use global shutter rather than rolling-scan shutter, or use a rolling-scan shutter faster than a monitor refresh cycle
4. Maximize screen brightness.
5. Pre-focus your camera (pause the motion test, lock focus, resume motion test)
6. Take photo.
If your smartphone camera is low resolution, bring phone closer, hold camera portrait -- and/or take three photos (top, center, bottom)
Stationary photographs are okay for strobe crosstalk tests, as long as the camera's exposure captures only one strobe flash (i.e. one refresh cycle's strobe flash), and your camera sensor scan is not slower than the display's refresh rate.

One thing I notice is your camera sensor is slow-scanning (taking 1/60sec) so it's creating additional disjoints mid-refresh cycle as different parts of your photographs (vertically) is capturing a different strobe. So it's hard to pre-judge for your screen.
