Hi Dray, Thank you for sharing your review. Your TV Works With Alexa, meaning you’ll need to connect a standalone Alexa device such as an Echo speaker, to control compatible smart home devices and some experiences on your TV. Here are the steps: 1. Download both the Amazon Alexa and Samsung SmartThings apps, if you don't already have them. Both are available for iOS or Android devices. 2. Make sure your Alexa device and TV are both connected to the same Wi-Fi network. 3. Your TV must be enabled within the SmartThings app. If not, make sure you are signed in with your Samsung account on the TV: Settings > All Settings > Samsung Account 4. Log in to the SmartThings app with the same Samsung account. Tap Devices, and if your TV isn’t already shown, tap + to add it to the app. 5. In the Alexa app, enable the SmartThings skill and sign into your Samsung account. This will automatically connect your Samsung TV to Alexa and let you use voice commands to control your television.

Hi, We appreciate your feedback regarding your U7900F TV’s performance. If you're experiencing freezing or lag in general response time, please try the following steps: 1. Check for firmware updates – Keeping your TV up to date can resolve many performance issues: Home > left directional key > Settings > Support > Software Update > Update Now 2. Run Device Care – This tool checks system memory, frees up cached data, and closes background apps that could be slowing things down: Home > left directional key > Settings > Support > Device Care > Start Device Care 3. Cold boot your TV – With the TV powered on, press and hold the Power button on your remote for 5+ seconds until the TV restarts. This helps refresh the system. If you're still noticing performance snags after these steps, please contact Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun).
