How can access viki?
Thank you for writing in to Viki Support.
As of 1 May 2018, the official Viki app on the Samsung App Store is no longer available. Any other Samsung Store apps with the 'Viki' name are not supported by us and you will not be able to stream videos there.
Instead, we can recommend other options to watch Viki from your TV, such as Chromecast, Roku, Apple TV, or using an HDMI cable.
For more information, you can refer to viki.com/apps for a list of TVs and devices that we do provide full support towards.
Hope this clarifies and feel free to let us know if you have any other questions or concerns.
