iOS7.0 or later.
This version conformed to iOS7.0 or later.
It changed that it was a camera screen -> camera roll -> photograph screen into the camera screen -> photograph screen so that the share with SNS or Cloud could be made quick.
If you want to share your photo with Instagram, Facebook and so on, Low photo quality (1280×720 pixels) would be enough and it enables quick upload and less packets.
When Photos application of iPhone was opened from this application directly and photos were deleted, the fault in which the afterimage of deleted photos remain was corrected.
