Tapping the fingerprint scanner keeps display awake on Android P

The feature appears to be part of Developer Preview 2

Google Pixel 2 XL fingerprint scanner

Android P lets you use the fingerprint scanner to keep the display from going to sleep — a welcome addition for mobile readers.

There’s nothing worse than tapping your screen to keep it from going to sleep and losing your spot because the text moved.

The feature works smoothly, as well. When the screen dims before sleeping, just tap your finger on the sensor. The phone doesn’t vibrate or respond to the touch, the screen just lights up again.

This is just one of the many small changes Google has made with Android P. Google also added fingerprint gestures to YouTube, added calendar and weather alerts to Ambient Display and put alarm and volume status into the notification shade. Together, the changes add up to some quality improvements. Sometimes, it is all about the little things.

Using the fingerprint to keep the display from sleeping appears to be part of the second Android Developer Preview. We tested the feature on our Pixel 2 XL running DP2 and it worked. However, the original Pixel running DP1 did not have the feature. It doesn’t work on Android 8.1 with these devices either.

If you’re running DP2 on your phone, give the new feature a try. Let us know if it works for your device in the comments below.
