What’s actually slowing this PC down?

On a Samsung Galaxy, turn on the phone’s Dark mode first: open Settings > Display > Dark, then reopen TikTok. This changes TikTok only if the app supports the device theme on your installed version. TikTok’s published instructions describe its built-in dark-mode setting for iOS and computers, not Android, so a dedicated TikTok toggle may not appear on your Samsung phone.
Turn on Samsung’s system Dark mode
- Open Settings.
- Tap Display.
- Select Dark.
- Reopen TikTok and check its menus and interface.
You can also swipe down from the top of the screen with two fingers to open Quick Settings, then tap Dark mode. Samsung says some third-party apps keep their original appearance, so TikTok remaining light does not necessarily mean the phone’s setting failed. The exact menus can vary by Galaxy model, software version, carrier, and region. Samsung’s Galaxy Dark mode instructions include the Display and Quick Settings routes.

Schedule Dark mode if you prefer
In the Galaxy Dark mode settings, Samsung documents options to schedule it from sunset to sunrise or set custom start and end times. Look for the schedule controls on the same Dark mode screen; their placement may differ across devices.

Why TikTok may not have its own dark-mode switch
TikTok’s published help page says its in-app dark mode is available only on iOS devices and computers. For those platforms, its documented path is Profile > Menu > Settings and privacy > Display; users can also choose to follow the device’s appearance setting. The instructions do not document an equivalent Android control, so do not assume that a missing Display option means you overlooked a Samsung setting. TikTok’s published availability can change with app updates or staged rollouts. TikTok’s dark-mode help page has the platform limitation and documented route.

Try Expanded dark theme on Android 16 or newer
If your Galaxy runs Android 16 or newer and exposes the setting, Android offers an Expanded option intended to darken more apps, including many without native dark-theme support. Check Settings > Accessibility > Color and motion > Dark theme, then look for Expanded. The path and availability can differ in Samsung’s software, and some apps may ignore the option or remain light. Google warns that expanded darkening can alter images and make text over images harder to read; its guidance also allows apps with appearance problems to be excluded. See Google’s Android dark theme and color inversion guidance.
What dark mode changes—and what it does not
Dark mode concerns interface elements such as backgrounds and menus, not the colors of TikTok videos. TikTok says its dark mode does not change video appearance, and Google says standard Android dark theme does not recolor media such as videos. Samsung Developer describes dark interfaces as using black or dark-gray backgrounds and menus, while noting that content can look visually jarring against them: Samsung Developer’s One UI theme guidance.

If TikTok still looks light
- Check the system setting: confirm Dark mode is on in Galaxy Display settings or Quick Settings, then reopen TikTok.
- Look for an in-app option, but do not expect one: TikTok’s published instructions do not list Android among the platforms with its built-in dark mode. Use the official, updated app, but an update is not a guarantee that an Android toggle is available.
- Consider Expanded dark theme only if available: it may affect more apps, but can distort images or reduce legibility; disable it or exclude TikTok if the result is hard to use.
- Find the setting by searching your menus: Galaxy screens differ by model, software, carrier, and region. Search Settings for “Dark mode” if the listed route is not present.
