Netflix is one of the primary sources of streaming content available, so if being able to access streaming content on this, or through other sources such as Amazon Prime or even YouTube, is an important factor, whether or not Netflix and other services can be used needs to be known.
The nabi 2S can use Netflix, assuming there is a valid account to use on the tablet. Apps that aren’t available to download in nabi Mode can be installed in Mommy/Daddy Mode, through such as Google Play and the Amazon Appstore, and added to the apps that children can use in their mode.
For online streaming sites such as YouTube, the site may need adding to approved sites in Mommy/Daddy Mode to allow children access to it.
