Hi, Thank you for purchasing the Samsung TU7000 TV. I am sorry to hear that you are experiencing issues with your 4K content on your new unit. The issue with the Apps may be related to your network connection and quality. We suggest you try the following: 1. Use 5G Wi-Fi if possible 2. Try wired LAN if available 3. Try repositioning the router so there are no obstacles between your TV and the router Please also be sure you are running the latest firmware. You can check to see what software version your TV is using and if there is an available update through the settings on your TV. Go to: Settings > Support > Software Update. You may want to enable automatic updates for conveniences. Select Settings- Support- Software Update, then select Auto Update. Additionally, to optimize the smart TV performance, please try Device Care option under the Support Menu. Go to Settings > Support> Device Care > Start Device Care. This improves your apps performance as it frees up unused cached memory and closes background apps.
