Samsung Smart TVs store temporary data (cache) for each app to speed up loading times. Over time this cache can become corrupted or oversized, causing apps to freeze, crash, or show outdated content. Clearing the cache fixes most app performance issues without deleting your preferences or account settings.

Clear Cache for a Specific App

  1. Press Home on your Samsung remote.
  2. Navigate to Settings (gear icon).
  3. Go to Support, then Device Care.
  4. Select Manage Storage.
  5. You will see a list of installed apps and their storage usage.
  6. Select the app with the problem (Netflix, YouTube, Prime Video, etc.).
  7. Choose Clear Cache.

On newer Samsung TVs (2021 and later), the path may be Settings, Support, Device Care, Manage Storage, then select the app.

Clear All App Caches at Once

  1. Go to Settings, then Support, then Device Care.
  2. Select Start Device Care or Clean Now.
  3. The TV analyses storage and clears cached data from all apps simultaneously.
  4. This process takes 1-2 minutes.

Reset Smart Hub (Deeper Cache Clear)

If clearing individual app caches does not fix the problem, resetting the Smart Hub clears all app data more thoroughly:

  1. Go to Settings, then Support, then Device Care.
  2. Select Self Diagnosis, then Reset Smart Hub.
  3. Enter your PIN (default: 0000).
  4. The Smart Hub resets and all apps return to their default state. You will need to log back into streaming services.

When to Clear the Cache

  • An app (Netflix, YouTube, Disney+) is crashing or freezing repeatedly.
  • An app shows a black screen when it should be loading.
  • The TV’s Smart Hub is slow to open or navigate.
  • Apps show outdated thumbnails or UI elements that do not match the current version.
  • A streaming app shows an error message about storage or data.

Preventing Cache Buildup

Run Device Care monthly to keep the cache from building up. On newer Samsung TVs, you can set Device Care to run automatically. Go to Settings, Support, Device Care, and look for an automatic maintenance schedule option.

Frequently Asked Questions

Will clearing the cache delete my Netflix downloads or watchlist?

Clearing the cache removes temporary files only. Your Netflix watchlist, profile, and account settings are stored on Netflix’s servers and are not affected. You will need to log in again after clearing app data, but nothing is permanently lost.

Does clearing the cache fix a slow Samsung TV?

Often yes. A clogged cache is one of the most common reasons Samsung Smart TVs slow down over time. Clearing it and restarting the TV usually restores snappier performance, especially in the Smart Hub and streaming apps.
