Do not assume you need the update. Go to Settings > Device Preferences > About > Software Version . If you see version 4.2.1 or higher, you are already on the top update. If not, proceed.

Depending on your specific model version, the update tab is usually tucked under "About."

Smart TV software updates often interrupt viewing, causing user frustration. This paper proposes an emotion-aware update scheduler that uses computer vision (facial expressions) and voice sentiment analysis to detect the user’s current emotional state. If the user is engaged (happy, excited) or neutral, the update is deferred; if bored, tired, or frustrated (due to UI lag or repetitive content), the update is triggered during a natural break. A field study with 120 households shows a 42% reduction in perceived interruption and a 28% increase in update compliance compared to fixed-time or random OTA updates.
