Someone did a linguistic analysis and demonstrated that there are two writers of Trump's tweets. Trump's were all the crazy ones, his handler's were all of the moderate ones and the ones that walked back what was said previously.

It was even easier than that at one point. The handlers and Trump had different mobile OSes

those are from a campaign staffer; twitter is not actually writing tweets for trump, or anyone else.

a handler is somebody who makes the blue check feel comfortable on the platform, e.g. banning people who disagree with them

I only know in the context of celebrities. Normally a handler is a person, manager, agent, personal assistant, who helps a celebrity deal with public appearances.

its more or less well known that Dan Scavino, Trump's social media dir, posts to Trump's twitter

You didn't even need to do that previously. Just hit the API and look if it originated on iOS or Android.

So does Trump use Android or iOS?

Trump had an Android phone while his handlers used iOS.

Other people have done longitudinal analyses and have talked about how there was also a shift in ~2011 as he launched the birther movement.

Trump didn't "launch the birther movement" which started before Obama even got the Democratic nomination, let alone as late as 2011.

Or maybe the opposite?
