Dear all, I would like you to implement the "Luma" noise reduction or Luminance noise reduction option in the raw development module since I tried it in the Raw Power program for iOS and it's amazing, I think you can implement that option in a future update ?

It's already there. Tap on detail and scroll down. The slider labeled "noise reduction" does luminance noise reduction and further down you'll find color noise reduction which does chroma noise reduction. In the desktop apps luminance is more clearly labeled as there is not enough space on the phone screen but they are the same thing.

I see that it works differently in Lightroom mobile, for example when I apply noise reduction this smoothes the image a lot in all areas of my image in general, on the other hand in raw power when I apply luma noise reduction this only reduces the noise in the parts of the image where there is luminance noise, but preserving the detail of the rest of the image

Noise reduction differs amongst tools but Lightroom's is quite good. You need to use not just the amount slider but also optimize the other two for your specific image. This can only be done zoomed to 100%. A quick google shows lots of tutorials on how to do this.

And many more. I haven't vetted any of these but a quick glance shows that they are fairly complete.
