3. Open Settings > All Settings > General & Privacy > Start Screen Options to deselect any apps you don’t want launching automatically when you turn on the TV. [4:37]
4. Perform a power cycle by holding down the power button on your remote until the Samsung logo reappears on the screen. [5:25]
5. Run a diagnostic test on your connection by going to Settings > Support > Device Care > Self Diagnosis > Smart Hub Connection Test. [6:46]
6. Reset your Smart Hub in the same Self Diagnosis menu using your PIN, which is usually 0000 if you haven’t changed it.

Ninja Tip: Disable “Intelligent Mode” in your TV settings, as this background feature constantly monitors your room’s light and sound levels, which can consume extra processing power and contribute to system lag.

If the performance issues persist, you can perform a factory reset by navigating to Settings > All Settings > General & Privacy > Reset.
