iPhone 6 old videos won't play
Hi,
Recently got a new iphone 6 running on ios 8.3, after having a 5S. Restored via itunes from my old backup, however some of my old videos saved to camera roll / snapchat album do not play, they simply have the loading circle that goes round and round but nothing happens, yet some play successfully as normal?
Everything else restored ok, pics music etc, just the videos that are causing a problem..
Can anybody help?
Much appreciated
iPhone 6, iOS 8.3
