Streaming devices

Smart TV apps are slow or freeze constantly

This is usually the TV's built-in processor and storage struggling with app updates over time, not a single broken app. Restarting and clearing cache helps, but older TVs may just be underpowered now.

  • PossibleToo many background apps or processes runningSome smart TVs keep apps running in the background, using up memory.
  • PossibleWeak Wi-Fi signal slowing app loadingApps that stream data can appear frozen while waiting on a poor connection.

What to do

  1. Restart the TV completely by unplugging it for a minute rather than just using the remote's power button.
  2. Go to the TV's settings and check for a system software update.
  3. Clear cache/storage for the specific app that's freezing, in the apps management menu.
  4. Uninstall apps you don't use to free up internal storage.
  5. Check Wi-Fi signal strength in the TV's network settings.
  6. If the TV is more than a few years old, consider connecting an external streaming device like a Roku or Fire TV stick.
  7. Factory reset the TV as a last resort if performance doesn't improve.
