A Photosphere is a 360 ° panorama photo, which could be downloaded as camera module in the camera app of the last Galaxy smartphones. Unfortunately, this module is no longer available on the Samsung Galaxy S8, so you cannot take photos with the camera app.
We would like to give you a tip, how it still works. However, you must access a photo app that is not available in the Play Store. Although this is the "surround shot" app from Samsung, however, this must be installed as APK.
Please download the Surround Shot APK as follows on your S8:
Once the APK is installed, it can be viewed in the camera app of your Samsung Galaxy S8. Swipe in the live image to the right and then select "Surround Shot".
Enjoy taking photospheres with the Samsung Galaxy S8.
