To control and manage your Samsung Gear 360 camera you need the Gear 360 Manager app that is only available for Samsung devices, meaning that the company’s 360-degree camera can’t be controlled using a non-Samsung smartphone. A member of the XDA developers forum has created a port of the Gear 360 Manager app that works with non-Samsung devices and even has forced 4K support.
Device lock has been removed from this Gear 360 Manager port which allows the app to work with handsets from the likes of Sony, HTC, Huawei, etc. Forced 4K video support means that the app does not downgrade videos to 2K for devices other than the Galaxy S7. To install this port on your device it needs to be running Android 5.0 Lollipop or higher and must have the Samsung Accessory Service installed from the Play Store. Full instructions and relevant cautions are detailed in the forum post.
