One of the things I liked the time I used iPhone as my main device was True tone. What is it? It is a technology that allows you to go automatically changing the temperature of the screen colors to match them with what you are seeing in the environment. Although for many it is somewhat irrelevant, the truth is that keeping it on greatly relieves the view by constantly looking at the phone.
As well, apparently the Pixel 4, the next Google phone, will incorporate a fairly similar technology. With the recent rumors we are learning that this device would have up to 5 sensors on the front, which would allow to have facial unlocking and, apparently, also something like True Tone.
The evidence comes from the code that has incorporated the latest Android Q beta, where the guys from XDA Developers they have found a line that does not refer to Pixel 2 or Pixel 3, so obviously It is intended for a terminal that we do not know yet.
If this ends up being true, the Pixel 4 would finally make that hardware level leap that many of its fans are waiting for. This considering that at the software level they have stood out a lot in recent years, but other devices such as the OnePlus 7 Pro or the iPhone XS Max continue to gain in the manufacturing and incorporation of this type of technologies.
