I have an iPhone 6. I frequently need to text EKG's to our cardiologists. This sometimes requires sending multiple EKG's (old ones, sequenced EKG's in the ED, etc.). I've noticed a bug with Messages that when I take a photo, send it, and then try to take another, the camera will show a black screen. If I hit the home button, double tap it, then close messages, I can then reopen messages and take another photo and send it. Has anyone else experienced this?
