If Photo Stream is not working for you, it is possible to disable Photo Stream on iPhone, iPad and Mac, without losing any of your Photos.
Disable Photo Stream On iPhone, iPad and Mac
Apple’s My Photo Stream feature allows you to share your most recent 1,000 Photos across all your devices (iPhone, iPad and Mac).
When you Enable Photo Stream on iPhone, Photos that you take on iPhone get uploaded to My Photo Stream on iCloud and become available on all your devices.
Similarly, Photo Stream downloads a copy of Photos from other devices on to the internal storage of your iPhone.
If you do not like Photos from other devices crowding the Photos App or taking up storage space on your device, you can easily disable Photo Stream.
Is it Possible to Turn OFF Photo Stream Without Losing Photos?
When Photo Stream is enabled on iPhone, only a copy of Photos that you take on iPhone gets uploaded to My Photo Stream.
Similarly, Photos from other devices that become available on your iPhone are only a copy of Photos available on the Original devices.
Hence, when you Turn OFF Photo Stream on iPhone, only the copy of Photos from other devices will be removed from iPhone.
The original Photos will still be available on the devices from which the Photos were uploaded to Photo Stream.
