We’ve all been there. You’re happily watching your favorite YouTube video when suddenly, out of nowhere, the screen switches to a bright white background.
If you’re like most people, you probably have a few questions about why YouTube keeps switching to light mode.

The answer is simple: YouTube wants the user experience to be as comfortable as possible for viewers.
The white background helps reduce eye strain and makes it easier to focus on the content of the video. Additionally, light mode helps users conserve battery power by reducing the amount of energy used by the device.
YouTube also automatically turns on light mode if it detects low-light conditions in your environment, such as being in a dimly lit room or using a laptop in direct sunlight.
This prevents users from having to manually switch back and forth between light and dark modes as they move from one setting to another throughout their day.
YouTube even offers users the option to keep light mode turned on at all times if they prefer it that way. To do this, simply navigate to “Settings” > “General” > “Appearance” and select “Always use light mode” from the drop-down menu.
3 reasons why YouTube keeps switching to the light mode
1. Clear data
One way to clear YouTube data is by going into the device’s “Settings” menu and selecting the “Applications” option. From there, scroll down until you find the “YouTube” app and select it. Once there, tap “Storage” and then select “Clear Cache.” This will delete any cached information stored on your device related to YouTube content that has been viewed.
Another way you can delete YouTube data is by using an app or tool specifically designed for clearing out old or unnecessary files from your device. There are several third-party options for this purpose, including Clean Master or CCleaner, which are both available for free in the Google Play Store.
These apps provide a much more comprehensive clearing of caches and other temporary files, which can help improve your device’s performance by freeing up storage space as well as memory resources.
Finally, if neither of these methods works for you, simply deleting the entire YouTube app from your device should also remove all associated data from it as well. Just be sure to back up any important playlists or videos before doing this so they don’t get lost permanently!
2. Use dark mode in OS
Once you have changed the theme of your device to use the dark mode, YouTube will also be required to use the dark mode and will no longer automatically reset to the light mode.

3. Update the browser or YouTube app
It is also possible to prevent YouTube from resetting to the standard mode by ensuring that the browser you use has the most recent update.
Check to see if you have the most recent version of your browser installed on your device; if you do not, you can download the most recent version of your browser from the Play Store or the Apple Store.
How to keep YouTube in dark mode
If you’re using YouTube and find that it keeps switching to light mode, there are a few things you can do to try and fix the issue.
First, try restarting your device or browser. This is often enough to fix the problem. If it doesn’t work, the next step is to check if you have any extensions or plugins that could be interfering with YouTube’s settings. If this is the case, disable these extensions or plugins and then restart your browser again.
Another possible cause of this issue is an outdated version of YouTube. To fix this, head over to the Play Store (for Android) or App Store (for iOS) and check if there is an update available for YouTube. If so, make sure to install it as soon as possible.
If all else fails, try logging out of your account and then logging back in again. This should reset any preferences that might be causing the problem and hopefully get rid of light mode once and for all!
The bottom line
Overall, YouTube keeps switching to light mode because it makes for a better user experience and reduces eye strain while viewing videos on its platform. If you find yourself frequently changing between modes or want something more permanent, remember that you can set your device up so that it always runs in light mode if desired!
