Use a darker theme on your Galaxy phone or tablet at night
You might not notice during the day, but late at night, your phone or tablet might as well be the sun. The bright screen makes you squint and can keep you awake into the wee hours. Don't worry, your Galaxy device has the solution. It's called Dark mode, or Night mode on older models. Set a darker theme on your phone or tablet, so you can use it more comfortably at night.
Note: Flickering may occur when using Dark mode or Night mode with certain apps. To prevent this issue, make sure to keep your device and app software up to date.
Manually turn on Dark mode or Night mode
Note: Dark mode may not work if you're using a downloaded theme, a high contrast font, or certain third-party apps.
When you use Dark mode, all your phone’s menus, settings, and preloaded Samsung apps will use a darker theme. Most third-party apps will stay the same, however.
First, swipe down from the top of the screen with two fingers to open the Quick settings panel.
Then, swipe to and tap the Dark mode or Night mode icon. The icon will glow when Dark mode is on.
To turn Dark mode off, tap the icon again.
On phones with Android 10 or later, you can also access Dark mode from the top of the Display settings screen.
Set a schedule for Dark mode or Night mode
If you forget to turn on Dark mode or Night mode sometimes, just make it automatically turn on or off at a set time.
First, swipe down from the top of the screen with two fingers to open the Quick settings panel. Then, touch and hold the Dark mode or Night mode icon to open its settings page.
Tap the switch next to Turn on as scheduled. Choose Sunset to sunrise to make Dark mode automatically turn on in the evening and turn off in the morning.
You can also choose Custom schedule to set your own schedule for Dark mode. Tap Start time, select your desired time, and then tap Done. Next, tap End time, select a time, and then tap Done.
You can also tap the switch next to Adaptive color filter to turn on the Blue light filter automatically between sunset and sunrise to reduce eye strain. However, this option is only available on phones running Android 10 or later.
Note: Even if you set a scheduled time for Dark mode, you can still turn it on or off manually whenever you want.
