THE CAMERA APP:
1) I hate the burst "feature". In iOS6, I could have my finger on the shutter button, and when I lifted my finger up, the photo would take. Now, if I keep my finger held over the button I get a bunch of photos by accident that I did not want to take.
2) The Video/Photo/Square/Pano slider is way to close to the shutter button. I have captured some photos by mistake just trying to change from photo to video. Who really wants "square" anyway? Whenever I shoot something for Instagram I much rather have the original full size photo anyway, and then just crop it in Instagram....
3) The flash button. When I press it, the options (auto, on, off) come up in white text overtop the screen. Today, I was shooting outside and the sky showed up as bright white at the top of the screen, where these buttons are when you tap it. They blend in. I couldn't even see the words. I had to point the camera at the ground, just so I could see the text and change my flash option!
NOTIFICATIONS:
4) in iOS6, when a notification such as a text came through, the banner would be at the top of the screen where the time/battery/etc. are. Now, it seems that the height of the banner is much taller, taking up more than just the time/battery/signal strip at the top. This covers up some buttons in some apps and I have to wait for the banner notification to disappear before doing anything again... wasn't this the whole point of banner notifications?
5) The weather does not always show up up in my notifications. Most of the time there is no text. And I miss the 7 day forecast with numbers and icons. Why just have text?
6) Why all the wasted space under calendar on the notifications if there are no events scheduled?
7) I don't understand the point of "All" and "Missed". Combine the two.
8) The Today/All/Missed bar at the top is not centered! I just find this sloppy....
OTHERS:
9) Fading in from a lock screen takes too long, if you are only quick checking the time.
10) The delay when going back to the home screen after tapping the home button.
11) Control Center is nice, but I wish we had the option to pick the apps at the bottom.
12) Auto-update apps should have "on wi-fi" only option. Otherwise, it's OFF
13) I wish in text messages, you didn't have to tap "load earlier messages" each time when you want to scroll back in time. Just load them auto when you scroll up to the top.
