I'm running build 10581 on my AT&T Lumia 1520, and every picture I take has a resolution of 1920x1080. I verified that the settings in the camera app have the 16MP option selected. Is there something else I need to do to get full resolution photos?
Weird. I have 10581 on my L1520 as well, and I'm getting 5k*3k photos (16Mpx). So...try setting it back to a lower resolution, taking a picture, then switching back to 16mpx.
Thanks - I just tried it and same thing. However, then I noticed that the file name on the phone had 'rich' in it, and that Rich Capture was turned on. Turning that off yielded the full resolution again. Thanks again.
