Did you pick up a Gear 360 after Samsung finally made it available in the US last week? It's a fun little camera and it's definitely going to take some getting used to taking photos of your entire surroundings.
In order to make sure everything runs as smooth as possible, it's a good idea to update the camera's software before you begin tweaking settings and taking 360-degree photos or videos.
The process takes just a few minutes, and requires you to have the Gear 360 app installed and setup on your phone.
With the camera's battery fully charged and connected to your phone, launch the Gear 360 app and tap on More > Settings. Then scroll to the bottom of the settings page, and select Gear 360 firmware version
Next, tap on Check for Update. A few seconds later the app will begin downloading the update. Once it's downloaded, your phone will transfer it to the camera's storage and ask if you want to install the update. Tap on Install and let the update finish.
As you can see on the release notes page, updating the software on your camera will reset all settings to their factory settings. Bummer, I know, but it's commonplace when updating a camera's software (my Fuji X-T10 does the same thing, for example), thus the importance of updating the software before you truly dig into the camera's settings and features.
Once the update is done, the camera will power cycle and reconnect to your phone.
