画面だけオフ на Андроид

This app turns off the screen after a few seconds when the proximity sensor responds without putting the smartphone to sleep.

Mainly, it prevents accidental taps in your pocket when playing positional games, reduces organic EL burn-in, and saves energy by cutting the screen display power, which should extend the battery life.

Similar apps already exist, but all of them immediately turn off the screen when the proximity sensor responds, and most of them malfunction and turn off the screen when calling up the top swipe menu (quick settings panel). So, I made a version that improved on that point.

■Notes as of October 2023
As of October 2023, the power saving mode of "Nobunaga's Ambition: Departure" is a specification that burns in organic EL, so we strongly recommend its use. The latest Dragon Quest Walk and Pokemon GO have power saving mode to prevent organic EL burn-in, so it seems safe to not use it.
