On Android there is https://www.motioncamapp.com/ which has been doing raw video for years.
The UI on the iOS Kino app is beautiful, crafted, and elegant. The UI on MotionCam (even after the update) is functional, brutalist, and purely an engineering driven, unstyled Android 4.4 UI elements style.
But MotionCam Pro gives full control, and even a RAW mode which wouldn't be possible on iPhone. You can even do ProRes (but it doesn't work very well for long unless you have a new phone with good cooling).
For the purpose I use it for (magnifying glass/telescope, using S23 Ultra), it's wonderful. But I always wished that the two worlds of Android and iOS development styles would collide for a moment....
