Netflix on Kurio7s

If you have a netflix account, you can use the netflix app. Or if you are an xfinity user, you can download the xfinity tv app, sign in with your details and youre good. Now if you want to watch movies added on your phone, you can download the VLC app. But if the movie format is not supported like the mkv format, you might need to convert them.

Not sure about your tablet, but generally if you delete an app or two and delete any cache that is stored you will be amazed how much space is freed up along with the benefit of it running faster.

If you need root access
1 .Enable developer mode and usb debugging:
