Apple’s Legendary White iPhone 4: Much Ado About White Paint
Who would have guessed that changing the
paint from black to white inside the iPhone
4’s glass body would cause such problems?
Obviously not Apple, which saw its original
June 2010 ship date for the white iPhone 4
fall almost a year behind schedule: the bright
white model arrived on April 28, with only
scant explanation from Apple executives as
to what went wrong. During the ten-month
delay, engineers redesigned the front proximity
sensor area, replacing a light gray-ish grid
of small dots with one big, black pill shape
that lets the iPhone 4 know when it’s about
to touch a face during a phone call. They also
added UV coating to prevent the white paint
from yellowing over time, and made other
under-the-hood tweaks to ensure that light
wasn’t leaking through the glass body out of
the screen or into the rear camera. Our tests
of the screen, proximity sensor and camera
found no significant differences between the
performance of the black and white versions
of the iPhone 4, with only minor distinctions
in how light was gathered by the camera in
pitch black surroundings. While it’s hard to
get excited about something that’s so late to
market, the white iPhone 4 is every bit as good
as the black one, and certainly rarer.
