If there is an issue on the Zattoo app of your Samsung Smart TV, please go through the steps of troubleshooting:
1. Disconnect TV from power supply
Switch off the TV completely and disconnect it from the power supply for about 10 minutes. This process resets the TV's internal memory and may fix an issue right away.
2. Delete the Zattoo App and reinstall it:
- Turn on your device and go to the Smart Hub Symbol
- Go to the Samsung Apps
- Search for Zattoo and select the App
- Delete the App and reinstall it by pressing the arrow button above the App-Icon and opening a little menu with the delete-option
- Restart your device and the App
3. Update the Firmware on your TV:
Go to "Menu" > "Support" > "Software Updates" > "Enter"
In case you have a device from 2012 and the Software-Update is not available with these instructions, you will need to update your TV manually with a USB-Stick. you can find further instructions here: http://www.samsung.com/de/support/ (enter the name of your TV model).
4. Reset the SmartHub:

5. LAN-connection instead of WLAN.
The App will only work properly if your Internet connection is stable. For a stable connection especially on big screens such as Smart TV, Nvidia Shield, Apple TV or Amazon Fire TV we recommend the use of a LAN-connection (cable). WLAN (wireless connection) can be affected by many factors and is more susceptable to errors than a cable connection.
