Upload to iCloud only
I have only 16 GB on my iPhone, but 200 GB on my iCloud space. At the moment, I have 80 GB worth of photos on iCloud, and my phone, even without any application installed, is completely full (I am optimizing iPhone storage as well).
How am I supposed to reach a workable solution? Is it possible to upload photos from the iPhone to iCloud only, without downloading photos existing on the iCloud? Is selective synchronization coming? It seems to me that is a very important feature, yet it isn't present. What good is to have 1 TB of iCloud space, if all my other devices have less than half?
iPhone 5s, iOS 8.3
