What is Galaxy S20 dark mode?
Galaxy S20 dark mode turns on a dark theme at the system level to alleviate eye strain, especially under low-light conditions. In the past, it was called night mode sometimes.
So, essentially, Galaxy S20 dark mode is the dark theme in other Android phones noticeable improvements.
The dark theme will try to use dark (black or grey) background and white text. This usually makes your eyes more comfortable when staring at the screen, especially when the light condition is not good.
Individual app developers may choose to implement the Android dark theme, or ignore it, or implement their own dark theme. So, by default, some apps may ignore the dark mode. In Android 10, you can force all apps to use the Galaxy S20 dark mode (read on).

So, when you switch to the dark background, the screen will utilize less power. For most owners, power saving is noticeable, and it is helpful to extend the battery lifespan slightly.
For most Galaxy S20 owners, there are three benefits of turning on the dark mode on Galaxy S20:
- Alleviate eye strain.
- Save battery.
- Aesthetic (depending on individual owners). Some users prefer white (light) background, and others may prefer the black (dark) background.

How to customize and schedule the Galaxy S20 dark mode?
In addition to turning on or off the dark mode on-the-fly, you can also turn on and off dark mode automatically and customize some aspects of Galaxy S20 dark mode.
As shown in the screenshot above, you can tap Dark mode settings (marked as B) to customize and schedule the dark mode.
In the dark mode settings page, as shown below, you can:
- Turn on dark mode based on a schedule.
- Apply dark mode to wallpapers.
- Apply turn on the adaptive colour filter.
Now, let’s go through them one by one.
Schedule dark mode
You can let Galaxy S20 turn on and turn off the dark mode based on a schedule.
There are two types of schedule for the dark mode:
- From sunset to sunrise. So the timing depends on your location and date.
- From start time to end time. You need to specify both the start and the end time.
Please note, you can always use overwrite the schedule on-the-fly as discussed earlier.
Apply dark mode to wallpaper
You can also apply the Galaxy S20 dark mode to the wallpaper, as explained here.
Apply adaptive colour filter
The dark mode can also trigger the blue-light filter on Galaxy S20.
By default, the blue-light filter is disabled. Once enabled, Galaxy S20 dark mode can turn on/off and adjust the filter based on the time.
Please note, the adaptive colour filter can be enabled and disabled only when the blue-light filter is disabled.
How to force all apps to use Galaxy S20 dark mode?
As mentioned, Android 10 formally introduced the dark theme support for individual apps.
However, app developers have the final say on whether their apps support the dark theme or not. So, there are many apps (not only old and outdated apps) in Play Store without dark theme support.
If you use any of these apps on Galaxy S20, the dark mode, by default, does not work for them. Consequently, you may open an app with bright interface in the darkness even Galaxy s20 dark mode. It can be frustrating.
Luckily, you can overwrite the app settings and force them to use dark mode when it is enabled in Galaxy S20 developer options.
Once the developer options are enabled, you can tap it on Galaxy S20 Settings page.
As shown above, in the Galaxy S20 developer options, you can find the Force Dark mode option.
Use the switch to enable it.
Now, all apps are in dark mode.
For example, as shown below, the Epson iPrint app does not support the dark theme.
But once you force it to use dark mode, it will look different, as shown above.
Basically, the Galaxy S20 replaced the white background to black. The text colour was also changed with some filters.
However, it did not change the images. So, if an app uses a white pattern or image as the background, the forced dark mode is unable to change its look.
In this example, you may notice the information icon becomes hard to recognize due to background change.
Anyway, you need to test it by yourself whether the app works properly when you force it to use the dark mode.
