Even with Android smartphone Lollipop 5.1 (ZTE Blade A452) I don´t have the possibillity to choose "Photo Sphere" - as there is not option like this. Only "Panorama" . . .
After quite some research, I´m sure that this feature -which is advertised as possible from any (!) Android smartphone with 4.4 or higher- needs some higher hardware requirements, which not so many smartphones meet.
Where can I find the at-least hardware requirements (or simply a list with all smartphones which are able to use the PHOTO SPHERE function of Google Camera?
