  Importance of updates

We regularly update your camera’s firmware and the DxO ONE application in order to improve reliability and performance. To avoid problems or to resolve those you might encounter, we strongly advise you to install all updates as soon as they are available.

• 
  To update your DxO ONE application, open the “App Store” application and open the “Updates” section. To not miss any updates, enable automatic updates (in the “Settings” application, “iTunes Store and App Store” section).

• 
  To update your firmware, see section “Application parameters”.

  Common problems and solutions

Problem: My DxO ONE screen is frozen and it no longer reacts to physical commands (shutter button, opening/closing lens cover, etc.).
Solution: Reboot your camera using the reset button (as per the procedure described in this section).

Problem: My camera won’t turn on.
Solution: Your camera may be out of battery. Plug it into a wall charger and check the charging indicator is displayed.

If nothing is displayed on the screen with your camera connected to a wall charger of at least 1000 mA (and not into a computer USB port), try the following procedure:

• 
  Leave your DxO ONE connected to the wall charger for at least 2 hours, even if nothing is showing on the screen.

• 
  Unplug the charger, then reboot your camera using the reset button (as per the procedure described in this section).

• 
  Plug your DxO ONE back into the wall charger and check the charging indicator is displayed on the screen.

Problem: When I plug my DxO ONE into my iPhone, the application doesn’t run automatically.
Solution: Reboot your iPhone. If you don’t have the time to do so, you can always run the application manually.

Problem: I’ve plugged in my DxO ONE and run the application, but I can’t access the capture screen.
Solution: Try one of the following solutions:

• 
  Check your DxO ONE is properly connected: the plug must be pushed fully home. If necessary, remove your iPhone case.

• 
  Reboot your iPhone.

• 
  Clean your iPhone Lightning connector.

Problem: My DxO ONE’s battery runs down extremely fast.
Solution: Read and follow the tips listed in section “Managing battery life”.

Problem: The DxO ONE application is no longer responding. I cannot access the gallery or take photos.
Solution: Try one of the following solutions:

• 
  Turn your DxO ONE off and then back on again.

• 
  Force the application to reboot as per the procedure described in this section.

• 
  Reboot your iPhone.

Problem: In Wi-Fi mode, the preview freezes.
Solution: Check the color of the frame around the screen:

• 
  If the frame is orange, the quality of your connection is poor. Try one of the following solutions:
  • 
    Bring your DxO ONE closer to your iPhone or Wi-Fi access point, or remove any obstacles that may be reducing the quality of the connection.
  • 
    Use a different Wi-Fi connection mode (see section “Shooting in stand-alone mode” for a more detailed description of the Wi-Fi modes).
  • 
    Turn off other nearby Wi-Fi devices.
• 
  If the frame is green, force the application to reboot as per the procedure described in this section.

Problem: I want to take some photos in stand-alone mode, but the screen is showing a Wi-Fi icon and I can’t access the capture screen.
Solution: If there are arrows on the left and right of the Wi-Fi icon, swipe the screen left or right to access the capture modes. If there are no arrows, plug your DxO ONE back into your iPhone, then update your firmware to use the arrows (see section “Managing battery life” for more information about updating the firmware).
