Shouldn't you just say?

Do you understand how modern smartphones work? There is no single really important detail provided in the description of differences between test and control phones. Not a single one.

Seriously, what do you know about how mobile phones work?

Basically, depending on used standard (2G/3G/4G at the time of study), phone model, direction of a call, method of "deactivating" phone and so on, there will be no any significant differences between "uninterrupted active call" on "silenced" phone and "deactivated phone".

And that 800-1900MHz band... :)

It is like a "study" about "influence of color on the behaviour of fleas" with zero information about color except that it was "popular".

That's really what matters.

Matters in what exactly? They didn't provide any real data about differences in setup between test and control groups. Their experiment is fundamentally unreproduceable.

And reproduceability is the only thing that matters in science.
