RGWW, Thank you for taking the time to provide feedback on your DU6900 TV. Please know that your feedback will be shared with our internal product teams. We take pride in our products and are sorry to hear that your experience was not up to our high standards. 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.
