Instagram update brings dark mode in iOS 13 (Update: Android 10 too)
UPDATE: Instagram announced support for dark mode is now available on Android 10 as well. Just like on iOS, there's no actual toggle in the app, so you'll have to enable dark theme for Android 10 to see it in Instagram too.
Still, you will not be able to turn the dark mode on or off within the application. Instead, the iPhone's system-wide settings are the ones that dictate Instagram's behavior, so if you choose to use the dark theme on your iPhone, the app will match it with its own.
We're not complaining, but it would have been nice to be able to switch it on and off directly from within the app. All in all, it's great that another popular iOS app is getting important visual improvements like the dark mode.
