Have you adjusted the splendid mode? This issue is caused by the new version of google photo album. It is recommended that you adjust splendid back to standard.
How to disable this splendid mode, I cannot find that option.
Where to find this splendid option. Not available.
Where to find ?
I have Google Photos latest version 18.104.22.1683006408 installed already for 5 days, I am using Wide Color Gamut, but didn't have problem with brightness increasing and decreasing when browsing in photos so maybe the issue is triggered by something else.I am using Google Play Services 18.3.85 (100400-262677519).
