Hi,
I've developed a small app to switch off the screen backlight without switching off the screen completely. It requires root.
This is an xda-exclusive free version! If you want to support me, please consider getting the paid version on Google Play or check out my other apps.
Please note: Redistribution of this app is not allowed!
Paid version on Google Play (same functionality): https://play.google.com/store/apps/details?id=com.cygery.screenbacklightoff
New: Now available via XDA Labs!
NEW: Video by MiroslavVitula: https://youtu.be/B7Wt3nIOdXg Thanks!
Review on NaldoTech: http://www.naldotech.com/turn-the-s...pting-videos-on-android-screen-backlight-off/ (Thanks!)
Device compatibility: second post
Why would I want to use this?
The typical use case is:
An often used workaround are apps which set the backlight brightness to a very low (but still visible) value and/or put an additional dark layer on the screen. On typical LCD displays both methods keep the backlight on. Thus, it will still emit light and use battery power.
This app turns off the screen backlight completely without switching off the screen.
Features:
How to turn the backlight on again?
Simply touch the screen.
What about OLED/AMOLED screens?
(Note: There are user reports where the app works on devices with AMOLED displays.)
An exception are OLED/AMOLED screens where the pixels itself emit light. I have no device with such a screen for testing. If you have one and test this app, please report whether it works or not.
It doesn't work!
Cheers,
cygery

Why would I want to use this?
The typical use case is:
- You use a video player app.
- You only want to enjoy the sound/music.
- Thus, you want the display to be off to save battery or because the brightness annoys you.
An often used workaround are apps which set the backlight brightness to a very low (but still visible) value and/or put an additional dark layer on the screen. On typical LCD displays both methods keep the backlight on. Thus, it will still emit light and use battery power.
This app turns off the screen backlight completely without switching off the screen.
Features:
- Notification to quickly switch off screen backlight
- Single or double tap to deactivate
- Option to automatically activate when screen turns off
- Configurable activation delay
- Configurable overlay color and transparency
- Timeout
- Floating activation button (optional, enabled via additional notification)
- Setting to keep screen on (usually not required)
- Shortcut (allows other apps, e.g., automation tools, to switch off the backlight via this app)
How to turn the backlight on again?
Simply touch the screen.
What about OLED/AMOLED screens?

- If you're using MIUI ROM: Please enable "Show popup window" for this app via the system settings.
- Make sure this app was granted root rights.
- Make sure that no brightness control or similar app interferes with this app.
- Do you know what the purpose of this app is? Please make sure before posting that "it doesn't work".
- Please take a minute to search the thread. If there's already an answer/solution this saves both of us time.
- Nothing helps? Post your device name, Android version, ROM name/version and describe exactly what you did, e.g., how you tried to use the app/what you clicked/etc.
Cheers,
cygery
