Documentation leaves a big clue about the possibility of flip cover cases for the Pixel 7 line

Written by admin

A Hall sensor is used to detect the presence of a magnet and the strength of the magnetic force. Phone manufacturers are putting this sensor on phones that are expected to have flip cover cases that use a magnet. When the case is closed and the sensor in the phone detects a strong magnetic field, it turns on the screen. If the sensor indicates that the magnetic field is weaker or absent (which happens with the cover open), the screen turns on. When the cover is closed, the magnetic field is stronger and the screen turns off.

The last Pixel models with a Hall sensor were the Pixel 2 and Pixel 2 XL from 2017. But Esper’s Mishal Rahman distributed a tweet stating that debug documentation includes a reference to a Hall sensor for the Pixel 7 series. If the upcoming Pixel 7 and Pixel 7 Pro come with a Hall sensor, it would be a sign that Google could include a flip cover as an accessory for the upcoming 2022 flagship Pixel models.

android police notes that the just-released Pixel 6a may also have a Hall sensor, as the handset’s software includes drivers for it. So far, however, there are no signs of the sensor in the new Pixel mid-ranger.
