http://androidforums.com – Good day. Earlier this year my son purchased a Note 2. I'd like to be able to use a keyboard, mouse, USB hard drive, and HDMI simultaneously. Is this possible? I have a 50% off cupon for Samsung accessories. I see they have a dock/keyboard combo I can purchase. The keyboard has a Samsung connector on it. I guess I can purchase a Samsung to HDMI adapter to it, but that still leaves me short a mouse and usb hard drive. I guess I can do a BT mouse, but then there is no USB port. What about a BT keyboard mouse combo, then use Samsung adapter to USB, for a HD or HDMI, but how can I do HDMI and (General)
