Do different Android camera apps produce different RAW/DNG files?

In general, the underlying RAW sensor data should be the same if the app is truly saving the camera’s RAW output through the phone’s API and the capture settings are identical.

What often differs is how the RAW is displayed or converted after capture. A RAW/DNG file is not a finished image; software must interpret it to produce a viewable photo. Different apps may apply different defaults for white balance, brightness, contrast, saturation, sharpening, or demosaicing when showing or exporting it, so the same RAW can look different.

That said, if one app is not saving the same kind of RAW capture, or is embedding different metadata or performing extra processing before writing the DNG, files can differ in size and quality. So “RAW” is often similar in principle, but not every app necessarily produces an identical DNG file.

Bottom line: if both apps are capturing the same true RAW stream, the sensor data should be essentially the same; visible differences usually come from interpretation, metadata, or additional processing.
