Samsung Galaxy S2 Accessories For Presentations

In this post we'll explore some effective presentations techniques using Samsung Galaxy S2 accessories. Use the Droid@Screen (See this blog post) program to display the mobile phone screen on my computer during my presentations. This program works by taking a continues series of screenshots of the phone screen. There are some problems with this design, there is noticeable delay during application interaction and the video performance is not great on my Lenovo X120e Ubuntu computer.

You can not demonstrate audio and video capabilities of the mobile phone using such software. Planning to give a talk about using Firefox Mobile with Android 4 screen-reader and existing solutions doesn't work for me.

Samsung Galaxy S2 HDTV Adapter

This adapter allow you to plug in your phone directly into HDMI large displays and digital projectors. The mobile phone AC charger powers the adapter and no additional audio cable is needed. The Samsung HDMI adapters are available for Samsung Galaxy phones and tablet models.

This works really great if you are planning to setup large screen display in a exhibition booth. Connect the phone to large screen display with HDMI cable and play your video demo in a loop.

Samsung Galaxy S2 Power Pack

The Samsung Power Pack comes handy when phone runs out of battery in the middle of the presentation. It does extend the battery life of the phone during the presentation or an extending application testing session.

Few caveats using these accessories. The HDMI adapter will not work when the phone is attached to the power pack .

This power pack has some issue with power sensing, sometimes it starts and stops charging with annoying beeps every 10 seconds. And you need to press locking mechanism tight to get the phone to charge. Hope someone at Samsung fixes this problem.


  1. i also like to have the usb OTG cable so you can plug in sticks that have presentations on them.

    (but psst, generally I just prefer my laptop)

    1. I haven't got the OTG Cable for Samsung Galaxy S II S2.

      Please watch this blog for upcoming post about presentations using mobile devices :)

  2. Otg and hdmi can't work together.
    And better use the 2000 mah battery than the pack

    1. That is interesting, Do you have any information about Samsung Galaxy S2 2000mah Battery?
