Have you ever found yourself looking at your old iPhone and thinking: ?how come the iPhone 4s was so good at the time??. At Forall Phones we feel the same way.
There is no doubt that technology evolves at a dizzying pace and with this post we will help you see the ?big picture? of Apple's evolution, from the iPhone 4s (2011 launch) to the iPhone 7 (2016) .
As incredible as it may seem, there are certain technologies that are here to stay, 326 ppi pixel density and an IPS LCD screen have been constant features since the iPhone 4s.
In terms of materials, the iPhone 4s had aluminum and glass, the 7 has mainly aluminum. Furthermore, the iPhone 7 is resistant to water and dust.
From the iPhone 4s to the 7 there was an increase in the cell phone's screen, going from 3.5 to 4.7 inches. One of the most fantastic improvements was at a photographic level: the iPhone 7 has a 12MP camera to compete with the 8 on the 4s and can record in 4k, whereas in the 4s era there was only full HD. In terms of the front camera, it went from 0.3 to 7 Megapixels and with HDR capability.
