    Oversampled 5mpx images are always made before jpeg compression so there's no difference.

    The 5mp pictures will always look better due to oversampling. Also it doesn't matter if you shout in 5mp +highres or 5mp +raw; the 5mp picture will always be the same.

    Off topic: Have you managed to catch a few Aurora pics? If so, I'd love to have a look at them.

    So, if i get it right, the camera shoots in raw format, and depending on the settings it oversamples and saves the 5mpx first and then saves either the RAW DNG or the JPG Hires image. depending on the settings i chose?

    Raw is the raw camera sensor data. It is then saved as highres jpg or dng and pureview oversample. Highres and pureview oversamples are saved from the same raw sensor data. Highres images doesn't need that much processing so they are propably saved during processing that 5mp pureview oversampled image.

    So what I'm saying is the order they are saved doesn't make a difference because each file is made from the raw sensor data anyway.

    It's really easy. 5 MP pictures are sharpened when scaling down from 38MP. This is a very common practice to sharpen the image while scaling down. And also goes vice-versa: to soften the image when scaling up (but this is advanced stuff).

    I produce 15MP pictures on my own from DNGs and I apply some sharpening (standard option withing the Lightroom).

    The 5 MP images does oversampling as part of the post-processing using the full resolution data it captures when rendering. The full resolution jpeg images don't have this. RAW files will have no post processing done by the phone at all, it's just a dump of the raw data the camera captures, so they'll look the most plain out of the camera (with the idea being that you can do the post-processing yourself with software).

    I don't know for sure, but I would have thought that the 5mp down-sampled jpeg, and the 38mp jpeg, were both produced from the 38mp raw image independently of each other.
