About FakeStandby

FakeStandby is an Android app that shows a black overlay over the running app to darken the screen while the device stays on and apps, including foreground jobs, continue running. It can be used to stay online in messengers such as WhatsApp, listen to YouTube videos, keep a game running, or maintain GPS tracking.

It uses Android accessibility services to display the overlay. The developer states it may not work on all phone models or Android versions, carries a risk of locking the user out of the phone, and offers limited power saving, especially on LCD devices with backlighting. The concept is described as working better on OLED or AMOLED displays.

FakeStandby FAQ

How does FakeStandby turn off the screen?
It launches an overlay over the current app using Android accessibility services and renders a black canvas. The phone stays on, so running apps do not notice the overlay.
Does it save battery on LCD phones?
The concept works better on OLED or AMOLED displays where black pixels are off. LCDs have backlighting that only turns off with the power button, and large savings should not be expected, especially on LCD devices.
What if the app does not work on my device?
It may not work on some models or Android versions. The developer tests on a personal device and cannot guarantee a fix, but users can report issues by contacting the developer or opening an issue on GitHub.
