"Modern cell phones, we observed a dozen years ago, are
“such a pervasive and insistent part of daily life that the
proverbial visitor from Mars might conclude they were an
important feature of human anatomy.” Riley v. California,
573 U. S. 373, 385 (2014). Since then, the percentage of
Americans who own smartphones has only increased. To-
day, more than nine in ten Americans own a smartphone.

(Nov. 20, 2025) (91%); compare A. Smith, Pew Research
Center, Smartphone Ownership—2013 Update (June 5,
2013) (56%)."
