The official Samsung page says that only iPhone 6s and newer devices are supported (although with limited functionality). I think this is just a marketing trick by Samsung. Theoretically, there is nothing Samsung devices can do that iOS devices can’t.
Great! Congratulations. Trusted with 50 spherical photos published on maps. But doing it as a business requires experience. Samsung gear for business is not bad.
I have the Gear 360 and an iPhone X. The Gear 360 is an ok camera. It is kind of slow though. It says 8 seconds wait in between shots but it is much longer while using the Google Street View app. The plus of the Gear 360 is that it is very cheap right now. You just have to be sure to get the 2016 version not the 2017 version as the 2017 version is not compatible with the Google Street View app.
That Fly 360 camera that others have mentioned might be interesting but I’m not sure if it is officially supported. The Ricoh Theta is a nice camera but much more expensive.
