Google recently added a Dark Mode to the YouTube mobile app (following Dark Mode for the desktop website), but there’s just one problem: iOS users get it first. Dark Mode is still “coming soon” to Android and we’re not exactly sure how long it will take. The good news is the Android developer community has once again come through for us. If you have root access on your Android device, you can get Dark Mode in the app right now.
This method requires modifying the a value in the shared-prefs in /data. That’s why root access is necessary. If your device is not already rooted, check the device forums for instructions. Once you have root access, you will need the Preferences Manager app and, of course, YouTube. Here’s how to do it:
When you open up the app again it should be in Dark Mode. The app will have a nice dark gray background and white-on-black icons. You can scroll through videos without the blinding white interface. Thanks to XDA member AL_IRAQI for sending in this method and providing screenshots.
