Another Google app has gone dark.
Google Pay is the latest Google app to get a dark mode. As noted by Android Police, version 2.96.264233179 of the Google Pay app will automatically switch to a dark theme when your phone has dark mode turned on or when battery saved is activated. There's no dedicated dark mode toggle in the app, so you'll have to do one of those two other things to enable it.
The update to Android 10 brings with it a system-wide dark theme, and so Google has been steadily adding a dark mode to its various Android apps in recent months. While Google Pay's dark mode is more of a dark gray than a true black, it will still help the app fit in with Android 10's dark mode and won't blind you with a bright white UI when you've got dark mode enabled.
This Google Pay app update is now rolling out, so be on the lookout for it.
