Google is working very hard to introduce the dark mode on its apps and Android OS. The buggiest implementation has been on Google Photos with the new dark mode. The problem is when the dark theme has been shown with a half-black and a half-white interface to Android Q. Also, the dark theme doesn’t have a turn-off setting for the app.
However, the UI issue has been fixed, and now the dark mode is rolling out to Android 9 Pie and Android 8 Oreo for Google Photos. The users that are using Android Pie and Oreo are having now their own system, and the dark theme enabled. If you are curious about the dark theme and if your Android Pie is equipped to receive it, you can do these steps: Go to Settings-Display- Advanced-Device theme – and turn on the dark mode.

On the other hand, you can always switch the themes automatically if you pick one dim wallpaper. The automatically turn will be used if you are an Oreo Android user, because the update doesn’t support manually selecting. So you can try your Google Photos and see the settings if they are switching off and on. Of course, this server-side change can last a little until the app is doing the job for you. So maybe using the latest version of the app could be helpful for you.
Also, if you didn’t know, the apps are connected, so maybe using the dark mode on another Google app, such as Messages, this action can trigger Google Photos as well. On the other hand, Google Photos doesn’t come with a toggle for its own dark mode in a system setting. Finally, take note that if you are an Android 9 Pie or Android 8 Oreo user, you can now take advantage of the dark mode for Google Photos.
