Hi everyone, I am an iPhone used from 1st Gen iPhone till iPhone 4s (then i switched to other OS). Now I purchased my latest iOS device the 6s plus ... and as expected it is awesome. The only problem which I am having is sometimes during normal usage i get this black screen (attachments) which goes away when I press any button. I am concerned if this is some sort of malware as I have never experienced this thing in the past, nor do I see any such issue reported online. Any advise / help please?
