There is a app that i used often for watching Korean Drama and Variety Shows. This app is called Viu which is a free app. However, you have to watch a short advertisement of around 30 seconds to 45 seconds before you can watch the selected show. Short advertisement will also be played in the middle of the shows.
The app can be found in google play store. Viu for Tablet is recommended. There is also a need for your Android Tv Box to be connected via wifi as Viu app will not work if the Android Tv Box is connected by lan cable. However, for Minix U1, this can be solved by enable disguising ethernet connection as wireless. Please click here for more detail on how this can be done.
Just install the app from google play store and you should be able to watch Korean Drama and Variety Shows. For some Android Tv Box, you might face problem when loading the show. The app will not load the selected show once the advertisement ends as shown below.
To solve this problem, you have to press the home button on your remote controller. For those who have the A2 lite remote controller, you can press the . By pressing this button, you will see the below screen.
