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.

Hi Lynn, Thank you for sharing your experience with low volume. There are several volume features you can adjust, which may improve your audio experience. 1) Auto Volume automatically adjusts the sound to a certain level when changing channels or switching to another external input. Go to Settings > All Settings> Sound > Expert Settings > Auto Volume. 2) Adaptive Sound automatically adjusts to a specific volume level while watching TV. The TV analyzes your volume usage history by time period to automatically adjust the volume when you use an app or switch to an external input source. Go to Settings> All Settings> Sound> Sound Mode> Adaptive Sound. 3) Several Sound Modes are likewise available to meet your personal preferences: Home > Settings > All Settings> Sound > Sound Mode. Also, some sources have their own volume control, which might need to be set higher. Please check the volume control of the external device (cable box or satellite box, DVD, Blu-ray, etc.) connected to your TV. Also, check the cable connection between an external device and the TV and then try the cable connection again. If you need more help, Samsung is here for you!
