You have a situation where a family member or friend has a problem with their computer and they look forward to you for help. With an Android phone (or tablet) and the free Teamviewer app, you can easily fix their computer problems sitting at your home remotely.

The desktop version of Teamviewer has to be installed on the remote computer (available for Windows, Linux and Mac) that you are trying to connect to. On every launch, the software will provide you with a unique TeamViewer ID and password – enter these credentials in the mobile app to connect with the computer. The connection is encrypted and secure.

Once connected, you can use the touchscreen of the phone like a multi-touch trackpad to control the computer’s mouse pointer remotely. There is gesture support (pinch to zoom, two finger scroll etc.) and keyboard input along with support for special keys like Ctrl, Alt, or even the Windows key.

The phone will show your current display screen and you can use the pointer to select and open files/folders. There is a visible lag of few seconds between the command given on the phone/tablet and its effect to be visible on the computer. You can optimize the display quality and the response speed from the settings depending on your network connection speed.

You can even transfer files between the computer and your smartphone/tablet. The interface is simple – you navigate to the folder, select files to copy and then and paste the files in the phone/tablet’s directory. A good thing is that the app supports transfer of multiple files simultaneously. You can even remotely reboot or shutdown a computer.

A free account lets you add computers in a group for quick access. You will have to setup a personalized password on each computer before it can be added in the group. This feature is useful for IT admins and helpdesks.

The free app is restricted for personal use only. TeamViewer supports multi-monitor setup and it can also remotely access computers behind firewalls and proxy servers.
