The idea that US citizens need to scrub their phones before entering the US is just a hysterical media narrative related to the drama around a certain middle east conflict right now (which I shall not mention because it will further devolve into a flame war).
I can tell you with certainty the amount of border agents who have a strong opinion about this certain middle eastern conflict is exceedingly small.
This seems to imply that public discussions about cleaning phones wasn't a meaningfully common occurrence before now.
But it's been a spontaneous topic for as long as devices have been at risk from border agencies - since at least 2017.

Where are you finding data for 2025?
"And you are an alarmist. You are saying that this must lead to this, and you can’t prove it. These are the beginnings, yes; but how do you know for sure when you don’t know the end, and how do you know, or even surmise, the end? On the one hand, your enemies, the law, the regime, the Party, intimidate you. On the other, your colleagues pooh-pooh you as pessimistic or even neurotic. You are left with your close friends, who are, naturally, people who have always thought as you have.
"But the one great shocking occasion, when tens or hundreds or thousands will join with you, never comes. That’s the difficulty. If the last and worst act of the whole regime had come immediately after the first and smallest, thousands, yes, millions would have been sufficiently shocked—if, let us say, the gassing of the Jews in ’43 had come immediately after the ‘German Firm’ stickers on the windows of non-Jewish shops in ’33. But of course this isn’t the way it happens. In between come all the hundreds of little steps, some of them imperceptible, each of them preparing you not to be shocked by the next. Step C is not so much worse than Step B, and, if you did not make a stand at Step B, why should you at Step C? And so on to Step D."
