Remote Release allows you to "remote release" your Canon EOS DSLR from your Android device with only a USB cable.

Wi-Fi support is also present, if your camera supports Wi-Fi or you are using a go-between like the MR3040 - see further details on the DSLR Controller website ( ) on how to setup the Wi-Fi connection.



Remote releasing is using a remote control to activate the shutter of the camera. This is to prevent shaking the camera, and is often used with bulb shots and/or tripods.

This app is the little (free) brother of DSLR Controller; see and

---- Features ----

- Activate the camera's shutter button from your phone over USB, just like using a remote release cable
- Enable/Disable Auto-Focus *
- Support for bulb shots (hold shutter button) *
- Support for continuous shooting (hold shutter button) *

* Depends on camera model. Requires a DryOS based camera. See DSLR Controller's device compatibility page ( )

---- Requirements ----

- An Android device with an ARMv7-A or newer CPU architecture (virtually all 1ghz+ devices)
- Supported Canon EOS DSLR

When connecting over USB:
- Not rooted: Android 3.1 or higher with USB host kernel+API support **
- Rooted: Android 2.3.1 or higher with USB host kernel support **
- The correct USB adapter, if applicable

** USB host kernel support can usually be determined by connecting a USB stick to your device, and seeing if the device recognizes it.

---- Devices ----

Please see DSLR Controller's supported devices page ( ) for device compatibility information.

----- Usage -----

-- Getting started --

- Install the application.
- Connect your camera to the phone/tablet, and turn it on. Half-press the shutter button if it was already on.
- If a popup comes up that offers to open Remote Release, press it, and move on to "Operation" below.
- If a popup does not come up, manually start Remote Release. A Superuser popup should appear, click allow. If this took more than a few seconds, Remote Release will complain it cannot find a camera, regardless if you have one connected or not. Exit the app, half-press the shutter button on the camera, then restart the app.
- If a popup appears that tells you your device is not compatible, this is the end of the line for you.

-- Operation --

After you have connected your camera and started the app, the app will show you the following:

- Camera model
- Current shutter setting (depending on camera mode)
- Current aperture setting (depending on camera mode)
- Current ISO setting (depending on camera mode)
- Current drive mode setting

Below that you will see three buttons:

- Auto-Focus button
- Shutter button
- Button to open DSLR Controller in the Market

If your lens is set to Auto-Focus and you are using a DryOS based camera, you can use the Auto-Focus button to select if focusing is triggered by pressing the shutter button. By default it is, but it is not always desired. If your lens is set to Manual-Focus, this setting has no effect.

Pressing the shutter button will take a picture on your camera. If the camera is set to bulb mode or to continuous shooting, press-and-hold the shutter button - the bulb/continuous capture will stop once you remove your finger from the screen.

    Works perfectly fine. I used on my canon eos 1100D. You just have to connect to your phone using a USB cable and a OTG cable

    I haven't used it yet, but the DEV is awesome so I'm confident that it works just fine.

    It works, well, sort of. . I installed it on 2 of my devices GTP6200 and GTN8000 both are not rooted and running 4.1.x Android. The app detects my camera (EOS 550D) just fine, however the issue is that on both my devices, it only allows me to take pi

    I tried relentlessly to make this thing work with my camera and the TP Link. It has no WiFi capability, and yet you're supposed to use this to test dSLR Controller? no dice. When I bit the bullet and bought dSLR Controller it did not work. I learned from
