Hi Billy P, If apps are not working correctly, we recommend first checking for firmware updates on your TV. Go to Home > Settings > Support > Software Update. If you do have the latest firmware, then you can next try a cold boot. There are two ways to cold boot your TV: 1) Using the Remote: For most people, the easiest way is to hold down the Power button on the Samsung TV remote until the TV turns off and then on again. This should take about 5 seconds. 2) Using the Plug: If you do not have the remote, unplug your TV from the wall outlet or surge protector, leave it unplugged for 30 seconds, and then plug it back in. For more help, please contact Samsung TV Support at 1-800-SAMSUNG, available 8 AM – 12 AM EST, seven days a week.

Hi there, Thank you for sharing your thoughts on the picture quality of your DU7200D TV. To ensure you’ve got the latest image quality updates, please confirm that your TV is up to date with the latest firmware version. You can check by going to: Home > Menu > Settings > Support > Software Update. If the picture you’re seeing is still not to your liking after updating firmware, there are several picture settings you may want to try adjusting. Go to Home > left direction button > Settings > All Settings > Picture > Picture Mode ...and select the mode that best fits your usage: 1. Standard: Is the default mode suitable for general viewing environments 2. Dynamic: Makes the picture brighter and clearer in bright viewing environments 3. Eco: Provided to save energy 4. Movie: Suitable for watching TV or movies in a dark room 5. Filmmaker Mode: Provides source content just as the creators intended. If the image is defined as Filmmaker Mode, it’ll automatically switch to Filmmaker Mode while watching. You can also fine-tune your picture with expert settings such as brightness, contrast, sharpness and more (All Settings > Picture > Expert Settings). I hope these tips help.
