your latest pictures are showing as square pictures, 642x642 pixels, so it looks like you have a square photo setting turned on. either through the app you are taking pictures with or in the phone settings for the camera. check for an "orientation lock", its job is to disable the gyros so the orientation never changes.
is there a camera icon visible? like this in the upper right corner?
make sure its right side up when you take the picture. if you turn the camera sideways it should switch. I know I am repeating myself and I am sorry, but I didnt have a picture of it
