Samsung's ToS,
> The Sites may allow you to share things like comments, photos, messages, or documents with us or with other users. When you share content, you continue to own the intellectual property rights to your content and you are free to share the content with anyone else wherever you want. However, to use your content on our Sites, you need to grant us a license for any content that you create or upload using our Sites. When you upload, transmit, create, post, display or otherwise provide any information, materials, documents, media files or other content on or through our Sites (“User Content”) you grant us an irrevocable, unlimited, worldwide, royalty-free, and non-exclusive license to copy, reproduce, adapt, modify, edit, distribute, translate, publish, publicly perform and publicly display the User Content (“User Content License”), to the full extent allowed by Applicable Law.
It's my understanding that "Sites" is all Samsung products as it is vaguely referenced in the ToS itself.
