Researchers have tried to identify the problematic usage patterns
that are related with smartphone overuse [5, 16], mainly
through self-reported scale which are subjective and prone
to recall errors [27]. Thus far, relatively little information
is known about how smartphone overuse is reflected in the
actual use of smartphones. In this paper, we investigate the
college students as a focusing lens on emerging technological
issues. Smartphones are used widely by college students. In
the first half of 2012, the smartphone adoption rates in the UK
and South Korea were 72% and 86%, respectively [2]. Moreover,
college students are considered to be vulnerable to technology
overuse because of their developmental dynamics and
relative independence from social roles and expectations [14].
