Do you mean syncing Contacts from your iPhone to iCloud? What is the issue specifically?
I have 2 iPhones synced with my iCloud account. Even though I checked sync Contacts on both iPhones, there are only contacts from my older iPhone synced on iCloud 🙁
 
On the newer iPhone, what do you see when you go to Contacts>Groups?
There is iCloud - All checked
[doublepost=1512050039][/doublepost]The strange thing is that the newest contacts I saved on my newer iPhone are also on the older iPhone but are not on iCloud.
