About this app

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

Remote Release also has a discussion thread on

---- 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.

It's all cool and good, pairing is easy and works well but there's no timer function. What's the point? Should I sit there for ten minutes and keep the button pressed all the time? I thought the whole point of these is so you can leave the camera unattended while shooting long exposure!

I tried using it with an Olympus camera even though it is not compatible with that brand, and the app recognized the exact model. Is there a way to use this with my E-PL6 regardless? Activating the shutter does not work, but the camera model is being displayed at the top. Thank you!

Works well. I tried it out with my Huawei P10 with A MICRO USB OTG and MICRO USB to USB C adapter into Canon 650D and it worked! Had to try a couple of different OTG cables (I had anyway). Super happy. Many thanks!
