Hi, everyone! 

At what screen brightness is recommended when editing on mobile for most accurate color and brightness?

I'm used to edit on computer with calibrated monitor and now would like to have the best experience on mobile.

Edit: already using the Natural screen mode. 

Any thoughts on this is also much appreciated! 

Thank you!
