Seven years. One upgrade.
Documented, dimension by dimension.

A side-by-side technical record of one personal device transition — display, silicon, memory, optics, power, radios, ecosystem. No editorial. No score.

Plot. Erase. Re-plot.

Plot of iPhone XR followed by Galaxy S25 FE in the same frame An animation that plots the front silhouette of an iPhone XR, then erases it and plots the Samsung Galaxy S25 FE in the same coordinate space — first device, then the second.
