I lost most of my pictures after backing them up in iCloud.
I restored my phone to factory settings because my clock is always messed up now I have another problem my pictures are gone. I am using iPhone 5c
Were you previously using iCloud Photos, and if so, is iCloud Photos enabled under your Settings > Apple ID > iCloud? If so, make sure the device is plugged in and connected to WiFi. As an added measure, make sure to go to iCloud.com via a browser and see if the photos are indeed in iCloud.
