While I am awaiting the return packaging of this phone (yes, cannot bear the visible fingerprint reader issue) I have noted something else while messing with the camera
You cannot turn off HDR in photos.
Normally, you take a pic and the HDR icon appears telling you it is going to get stuck in after you take the shot. Take the phot and view it and you can see this happen.
Now, in the camera settings, turn off the "HDR (rich tone)" option and the icon no longer appears when you are taking a photo.
Take another photo with HDR and look for yourself
HDR kicks in and the 2 photos look IDENTICAL
And yes, the scene optimizer is completely off.
Was this a complete rush?
