Preview Compatability Matrix


How to fix it


1.  Make sure that you’re within range.
You want the Wi-Fi icon in your App to show at least 2 bars to be sure that you’re within range (~30-50ft). If the preview does not show up when the user is controlling the camera at a distance, this could be attributed to packet loss. In order to transmit a video to the preview screen, the GoPro will send multiple packets that contain data to compile the video for preview. Packet loss occurs when one or more packets of data traveling across a network fail to reach their destination (e.g. Packets traveling from the camera do not reach the mobile device). Packet loss is typically caused by network congestion. If the user is experiencing packet loss, the user will likely see a choppy preview screen prior to not seeing any preview at all.

2.  Close / Kill and re-launch the App.

iOS - Double tap the home button and swipe the GoPro App screen up to quit the app

Android - Due to the variance of Android devices, please reference this third party tutorial

Windows - Press and hold the back button on the phone and select the X in the upper right corner of the application

3.  Make sure the GoPro App is up-to-date.

5.  Test with your device’s Airplane Mode turned ON.

In most cases, Preview doesn’t start when your device’s APN profile prevents the GoPro App from working properly. This can also be attributed to network inference by surrounding wireless devices. To test for this, forget the GoPro Wi-Fi network on your device, turn ON Airplane Mode on your device, remove/reinsert the camera’s battery, and power on/off the Wi-Fi BacPac (for HD HERO2 camera).  Next, reconnect your device to the GoPro Wi-Fi network.  

Launch the GoPro App.  If you can see Preview with Airplane Mode ON, this means that you either need to uninstall your APN profile if you’ve downloaded apps that affect data, like Onavo, Snappli, or APN-Switch – OR – the user is in a location with significant wireless interference which can result in packet loss.

Also be sure to check your carrier’s data plan.  If they don’t allow streaming video, you’ll need to turn ON Airplane mode to view Preview on the GoPro App. Also turn off any Firewall apps, such as Droid Wall. If this doesn't work, check with your carrier to see if they've disabled video streaming on your device.  We’ve seen this with some prepaid carriers.


6.  Make sure the camera software is up to date on your HERO4, HERO3, or HD HERO2 camera (and your Wi-Fi BacPac if you’re using an HD HERO2 camera).

For your HERO4, HERO3+, HERO3 camera or HD HERO2 camera, you can do this verifying your version.txt file against the current camera software releases by visiting the Software Update Release Information page.
