Which display brightness on mobile devices to edit?

[#1]

Hello,

Since a few weeks I am using Lightroom CC classic on my desktop and Lightroom CC mobile and I am excited!

But I am struggling a little bit with editing on my smartphone. The ambient light sensor of my mobile controls normally the brightness of the display and if I forget to set it manually for example to the middle I edit pictures and they will be too dark.

How do you handle this? Is there anything available like the DataColor Spyder for mobiles? Or is there any workaround?

Many thanks!
