Why Does YouTube Keep Switching to Light Mode?
Some users encounter the frustrating issue of YouTube constantly switching back to light mode. Why does YouTube keep switching to light mode? Here are some reasons to convenience you to solve them.
Reasons 1: Cached Data
One of the most common reasons YouTube keeps going light mode is the cached data. When you use YouTube, the app or browser stores certain data, like images, scripts, and settings, in its cache to load the page faster in the future. If the cached theme-related data is incorrect, it might override your dark mode selection and force the light mode to be displayed.
Reason 2: Outdated App or Browser
If your YouTube app is not up-to-date, it may malfunction, causing YouTube’s dark mode to constantly switch to light mode.
Reasons 3: Multi-Device Usage
If you use YouTube on multiple devices and have enabled syncing across these devices, a problem with the sync process could cause the theme to misbehave. One device might end up with the incorrect light mode setting, even though you have set dark mode on both.
Reason 4: System-Level Theme Changes
If your device’s theme is set to automatically change based on time or light conditions, YouTube might follow this system-wide setting even if you have manually selected dark mode within the app.

Light Mode or Dark Mode
YouTube’s light mode and dark mode have their own features. The choice depends on personal preference. Following is the introduction for these two modes.
Light mode: Features a predominantly white background with darker text, which gives it a bright and clean look. This design offers a more traditional and familiar interface, making it easier to see details and colors clearly.
In well-lit environments, the light mode can be comfortable for the eyes as it matches the surrounding brightness. However, in a low-light environment, the light mode is too harsh, causing eye strain.
Dark mode: Features a black background with lighter text. It provides a sleek and modern appearance, and the contrast between the dark background and light text can make the content stand out. The darker background is gentler on the eyes, making it a better option for watching videos in bed or in a dimly lit room.
