I'd love to take more pictures with my iPhone 6s plus, but I can't see the screen to see what the picture would be!! I've seen other people's pictures and wonder how they do it????
It's normal for not being able to see the screen under bright sunlight..
I usually just snap a few photos, and then when I'm back at home I just edit them.
I can remember my first digital camera and camcorder being that way too. But at least I could use the view finder! Guess I'll just hold the phone up and snap pictures and hope for the best ? ha ha!
