Phone screen (Pixel 7 Pro) dimming constantly and randomly when editing photos at max brightness

Issue: Google Pixel 7 Pro screen dims unexpectedly when editing photos in Lightroom mobile, when screen is at max brightness with adaptive brightness OFF. It is not an overheating issue (happens when phone is cool) and it only happens in Lightroom mobile.

Lightroom Version Number: 8.3.2

OS Version Number: Android 13

Steps to reproduce:

1. In phone settings, turn adaptive brightness OFF and brightness level to 100, make sure Night Light is OFF as well

2. Open a photo to edit mode in Adobe Lightroom

3. Begin editing the photo, going through all of the "light" settings first, then "color", then "effects" "detail" and "crop" in no specific order, and wait for the screen to dim 

Expected result: Ability to edit the photo with consistent selected brightness level

• Actual result: Screen dims throughout editing process repeatedly and randomly, rendering the app useless as an editing tool
