Pixel 4 vs Pixel 3: All the major differences
This change is a really pleasant surprise coming from Google. A high refresh rate display is something many manufacturers seem to consider a feature they can easily pass on. To be fair, there’s a good reason for that, some people can’t even tell the difference between a 60Hz and a 90Hz display. The difference is there, however, and while it's almost impossible to showcase it through the internet, when using a 90Hz display in person you notice that scrolling and other animations are smoother than usual.
One concern that usually comes with the higher refresh rate is a reduction in battery life. Hopefully, Google has done a good job on the software side to keep things optimal depending on the use-case, after all, there are many situations in which you don’t need 90 frames per second.
New telephoto camera
The new telephoto camera comes with a 16MP sensor, a 2x optical zoom, optical image stabilization and phase detection autofocus. Google has also woven in some of its clever code to give you a better hybrid zoom. When using it, the optical zoom and digital zoom are combined to bring objects closer while keeping them sharp. During the presentation it was specifically stated that it's better to pinch and zoom before taking the shot rather than cropping parts of the image afterwards, when the algorithm can't help improving the quality.
3D Face unlock
Google is following the steps of Apple and is ditching the fingerprint sensor in favor of 3D face recognition. Fortunately, Google decided against having a big and ugly notch and housed all the tech in the top bezel instead. The new face unlock will use an infrared dot matrix projector and a camera to go along it. This will make it almost impossible to spoof unlike other face unlock technologies that take pictures with the selfie camera. The question remains how fast it will work but we’ll test that soon enough.
This page Google has taken from the LG book but put its own twist on it. Part of Google’s new Motion Sense technology is a tiny radar that’s also built in the top bezel and precisely detects the movements around your phone. Quick Gestures will allow you to control certain functions of your smartphone by gesturing with your hand in front of it: changing songs, adjusting volume and so on. We’re always skeptical when companies implement features like that, especially on a device that you’re using by holding in your hand. No matter how cool demos make it seem, the reality is often far from ideal to the point it’s not even worth using. Still, Google seems to be confident about its implementation so hopefully this time we’ll get something more useful.
