On the technical side, the sensitivity and rate of light sensors heavily vary between smartphones. As far as I know, we have not seen rates beyond 10 Hz, more likely lower.
For a start, I would check how precisely the time between to flashs could be measured and if you observe differences when switching the two stopwatches. I wonder if the smartphone torch would work better as a signal?
