Small issue when viewing photos

[Tofty]

Hi, I only got my Xperia Z2 today and I've noticed something going on when i view photos that wasn't happening earlier. When I take a photo with the camera in the camera app it's fine and looks good, but then when I go to view it by pressing the little thumbnail in the camera app the photo is always displayed in landscape and for some reason seems to dim and darken considerably after a second or two. This only happens when i view the photo in the camera app, if I exit the app and go to the photos app it works fine.  Anyone know why this happens and how to change it? Is it some sort of power saving thing because I'm at around 1/3 battery? Any help is appreciated

what if you try

settings > apps > all > camera  > clear data > check again

That's done the trick! Thanks very much
