How to Enable Dark Mode on X / Twitter

You can turn on X dark mode from X’s own settings on the web, iPhone, iPad, and Android. On x.com, open More → Display. In the mobile app, open Settings and privacy → Accessibility, display, and languages, then select the display menu and turn on Dark mode.

Some search results still say X dark mode is controlled only by your phone. That information describes a brief iOS change from early March 2026. X restored the manual iOS toggle about a week later, and its current help pages again document in-app controls for iOS and Android.

X Dark Mode: The Quick Steps

On x.com in a desktop browser

1. Sign in at x.com.
2. Select More in the left menu.
3. Select Display.
4. Choose the dark background shown for your account. X Help lists Dim and Lights out, although many web users lost the Dim option in February 2026.

If Display is not listed directly, go to More → Settings and privacy → Accessibility, display, and languages → Display.

In the X app on iPhone or iPad

1. Open X and tap your profile menu.
2. Tap Settings and privacy.
3. Tap Accessibility, display, and languages.
4. Tap Display and sound.
5. Turn on Dark mode and select the dark appearance available in your app.

You can also open the profile menu and tap the light-bulb icon for a faster route to the theme controls.

In the X app on Android

1. Open X and tap your profile icon.
2. Tap Settings and privacy.
3. Tap Accessibility, display, and languages → Display.
4. Tap Dark mode.
5. Turn it on, or select Use device settings if you want X to follow Android’s theme.
6. Select Dim or Lights out if those choices appear in your app.

What Happened to Dark Mode on X?

X made two separate changes in 2026, and outdated search results often combine them.

First, X removed the softer blue-gray Dim option from the web for many users in February 2026, leaving the light theme and the darker Lights out appearance. Nikita Bier, who was X’s head of product at the time, said the company could not support more than two colors and was considering making the web’s black theme lighter.

Then, in early March 2026, X briefly removed the manual dark-mode toggle from its iOS app. Nikita Bier said the app would instead follow the operating system because the app-level control had caused issues. Around March 12, X restored the manual iOS toggle after user feedback. Bier acknowledged the reversal by sharing a post that said, “We all make mistakes.”

The removal was therefore temporary on iOS. Contemporary reporting found that Android still had its own theme controls during the iOS change, and X’s current Android help page continues to document them. There is not enough evidence to say that Android followed the same removal-and-restoration timeline.

In short:

• Dark mode is available on x.com, iOS, and Android.
• The iOS manual switch was removed briefly, then restored.
• The middle “Dim” theme disappeared from the web for many users. X’s current Help page still lists it, so the documentation and live menu may not match.
• Old instructions that describe mobile as system-only are now outdated.

How to Turn On X Dark Mode on a Computer

The mobile app changes did not remove the separate display setting from x.com on a desktop browser.

1. Open x.com and sign in.
2. Select More in the left navigation.
3. Select Display. If you do not see it, open Settings and privacy → Accessibility, display, and languages → Display.
4. Under Background, select the dark option shown for your account.
5. Close the display panel. X should apply the change immediately.

The darkest web theme is labeled Lights out. Many users lost the softer blue-gray Dim background in February 2026, while X’s current general FAQ still lists both Dim and Lights out. Because the documentation and product menu do not fully agree, use whichever dark choices appear for your account.

How to Turn On X Dark Mode on iPhone or iPad

Current versions of X for iOS again provide a manual dark-mode control inside the app.

1. Open the X app.
2. Tap your profile menu.
3. Tap Settings and privacy.
4. Tap Accessibility, display, and languages.
5. Tap Display and sound.
6. Turn on the Dark mode slider.
7. Select the dark appearance shown in your version of the app.

For a shorter route, open the profile menu and tap the light-bulb icon. X’s Help Center says this opens the dark-mode settings directly.

Make X follow the iPhone or iPad theme

If the in-app control is missing or you prefer a system-wide setting, open the device Settings → Display & Brightness → Dark. You can also turn on Automatic to schedule the system appearance. Close and reopen X if it does not update immediately.

How to Turn On X Dark Mode on Android

X’s current Android documentation provides both a manual dark-mode setting and an option to follow the device theme.

1. Open the X app.
2. Tap your profile icon.
3. Tap Settings and privacy.
4. Tap Accessibility, display, and languages → Display.
5. Tap Dark mode.
6. Turn on dark mode, or select Use device settings.
7. Choose Dim or Lights out if both options appear.

X’s March announcement about system-level theme control was prompted by the iOS change. Contemporary testing still found the Android toggle at that time, so this article does not assume Android went through the same rollout.

Make X follow Android’s theme

Select Use device settings inside X, then open Android Settings → Display and turn on Dark theme. Menu names can vary by phone manufacturer, and many devices also have a Dark theme tile in Quick Settings.

If the X display controls are missing, update the app first. The system setting remains a practical fallback while your app version or account receives the current menu.

How to Keep x.com Dark Without Changing Your Device Theme

X’s restored mobile controls let you keep the app dark while the rest of your phone stays light. In a browser, Night Eye provides additional control over x.com’s appearance.

Night Eye lets you set a dark appearance for x.com in a supported browser without changing the operating system theme. It can also adjust brightness, contrast, warmth, and dimming for the website.

1. Install Night Eye for your browser.
2. Open x.com. If the site was already open during installation, refresh the tab once.
3. Select the Night Eye icon in the browser toolbar.
4. Choose Dark Mode for a full dark conversion, or Filtered Mode to keep X’s colors while reducing brightness and adjusting contrast or warmth.
5. Save the settings for x.com so they do not change other websites.

This is especially useful if the native Lights out theme feels too dark or if the Dim option is no longer available to you.

Night Eye works at the browser and webpage level. It does not change the native X app on iPhone or Android. On iPhone and iPad, you can use Night Eye with x.com in Safari after enabling the Safari extension and granting website access.

What to Do If X Dark Mode Is Gone or Not Working

The X app turned light after an update

Open X’s display settings and turn Dark mode back on. The manual iOS toggle disappeared briefly in early March 2026, but X restored it around March 12. If you still cannot find it, update the app and use the phone’s system dark theme as a fallback.

Your phone is dark, but X is still light

1. Open X’s Dark mode settings and select Use device settings if that option appears.
2. Confirm that the phone is set to Dark, not an automatic schedule that is currently in its light period.
3. Update the X app from the App Store or Google Play.
4. Close X completely and reopen it.
5. Restart the phone if the app still does not refresh its appearance.

If the issue continues, open x.com in a browser and use its display setting as a temporary alternative.

The Dim option is missing on x.com

The missing option is likely connected to X’s February 2026 web-theme reduction. This was separate from the brief iOS toggle removal. X’s current Help page still lists Dim, but many accounts show only Lights out. Use the options actually displayed for your account, or use Night Eye’s Filtered Mode, brightness, and dimming controls for a softer browser appearance.

The in-app dark-mode setting is missing

Update X from the App Store or Google Play, close it, and reopen it. Current X Help pages document manual controls on both iOS and Android. If your build still lacks the menu, set the phone to dark mode under iOS Settings → Display & Brightness or Android Settings → Display until the current controls appear.

Frequently Asked Questions

Does X still have dark mode?

Yes. On x.com, use the website’s Display menu. On current iOS and Android apps, open X’s display settings and turn on Dark mode. You can also choose Use device settings where available.

Why did Twitter remove dark mode?

X briefly removed the manual dark-mode toggle from its iOS app in early March 2026. Nikita Bier, who led X product at the time, said the app-level control had caused issues and that iOS should control the theme. X reversed that decision about a week later and restored the toggle after user feedback. Dark mode itself was never removed completely.

What happened to dark mode on X?

Two different events were mixed together in search results. X removed Dim from the web in February 2026. It then briefly removed the manual iOS dark-mode switch in March, announced system-only control, and restored the switch around March 12. Current iOS and Android help pages again show in-app dark-mode settings.

Why did X remove the Dim theme?

The Dim theme was a softer blue-gray option between the light theme and Lights out. When it disappeared from the web for many users in February 2026, the company’s product lead said X could support only two colors at that time and was considering a lighter black for the remaining web dark theme. X’s Help page still lists Dim, so check your live Display menu: some accounts may not match the documentation.

Can I make only the X app dark while my phone stays light?

Yes. Current X help pages document a manual dark-mode switch in both the iOS and Android apps. Turn on dark mode inside X rather than selecting Use device settings. If the menu is missing in your build, update X or use x.com in a supported browser until it appears.

Does Night Eye change dark mode inside the X mobile app?

No. Browser extensions cannot restyle the native X app. Night Eye changes x.com when you open it in a supported browser. On iPhone and iPad, that means using x.com in Safari with the Night Eye Safari extension enabled.

Are X and Twitter dark mode the same thing?

Yes. Twitter was renamed X, so older instructions may refer to Twitter dark mode, while current menus and support pages use X. The relevant service is now x.com and the X mobile app.

Choose the X Dark Mode Setup That Fits You

Use X’s native Display menu on a computer and its in-app Dark mode control on iOS or Android. If you want more control over x.com than Lights out provides, install Night Eye and save a separate browser appearance for X.
