You can download the app software by computer, copy the installation package into a USB flash drive, and then insert the USB flash drive into the USB port of the TV. Some TVs will automatically detect the USB flash drive and then pop it up. Some TVs need to operate and find the installation package by themselves, or install the app in the app store through Samsung's app market. SamsungApps has many options or press the SMARTHUB button of the remote control to enter the intelligent interface, and then select the content of interest in the application interface to enter the download page and download.
