Every time a smartphone slides into a pocket or rests on a table edge, a fine line etches into the screen. This scratch is narrow, often thinner than the edge of a fingernail.
These moments repeat throughout the day. The screen brushes against fabric, keys, or wooden surfaces. Each contact adds another mark, stacking silently onto the glass.
Days turn into weeks, and the repetitions continue. Scratches begin to intersect, forming patterns of lines that spread across the display area.
The surface now bears dozens of these traces. They layer in rows and crosses, built from countless small grazes. In direct view, the glass retains its smooth gleam.
Under angled light, the accumulated lines catch and reflect. This collection grows with every pocket dip or tabletop set-down, filling the screen steadily.
The phone's face carries this ongoing buildup. Marks from repeated everyday touches remain, woven into the material without shifting its daily appearance.
