Quick answer: To disable Incognito split-screen in Chrome for Android, open chrome://flags, search for Android Incognito Split Screen, set it to Disabled, and tap Relaunch. The split-screen option for Incognito windows will no longer appear.

Chrome on Android lets you use split-screen with an Incognito window, but not everyone wants that option around. Whether you are setting up a shared phone or just want to limit Incognito access, you can turn it off with a Chrome flag.
What you need before you start
- Google Chrome on an Android phone or tablet.
- Access to chrome://flags, Chrome’s experimental settings page.
- Time needed: about one minute.
Good to know: Chrome flags are experimental. The Android Incognito Split Screen flag may be renamed or removed in a future Chrome update, and flags can reset after a major update, so you may need to repeat these steps later.
How do I disable Incognito split-screen in Chrome for Android?

- Tap the dropdown next to it and select Disabled.
- Tap the Relaunch button at the bottom of the screen.
Chrome restarts, and the Incognito split-screen option is no longer available.
How do I turn it back on?
Go back to chrome://flags, search for Android Incognito Split Screen, and set it to Default or Enabled. Tap Relaunch and the option returns.
Frequently asked questions
Does this affect regular split-screen too?
No. This flag only controls split-screen with Incognito windows. Regular split-screen with normal tabs still works as usual.
Why can’t I find the Android Incognito Split Screen flag?
Chrome flags change between versions. If the flag is missing, your Chrome build may be too old or too new, or the flag was renamed or retired. Update Chrome from the Play Store and search again.
Will the flag stay disabled after a Chrome update?
Not always. Major Chrome updates can reset flags to their defaults, so you may need to disable it again after Chrome updates.
Wrapping up
Turning off Incognito split-screen in Chrome for Android takes about a minute through chrome://flags, and reversing it is just as easy. Keep in mind that flags are experimental and may reset after an update.
