Yes, so you either get a strobe on/strobe off every two frames if you're in 60 Hz country, or a slower crawling flicker in 50 Hz land. Migraine-inducing either way. Also, your phone won't shutter at exactly 60.00/50.00 Hz (mains freq. is pretty stable, usually stable to at least the first decimal) so you'll see a jittered, jumpy phase drift on top of that.
Yep, and this breaks all sorts of computer vision setups. We had to compensate for it on the cameras that track the Oculus controllers, since folks are often playing under indoor lighting
