Dark themes are becoming extremely popular in recent months thanks to both Google and Apple adopting dark modes in Android 10 and iOS 13 respectively. Finally the latest alpha update of the Instagram app on Android has added a dark theme. Better yet, it’s an AMOLED dark theme so the background colors are black.
If you want to enable this on your phone, you need to first update to the latest version of Instagram (linked below) and then enable your phone’s built-in dark mode because it currently follows the system-wide toggle. That means it’ll work if you’re running any Android phone on Android 10, if you have a Samsung Galaxy device running One UI or Xiaomi device running MIUI 10. I tested Instagram’s dark theme on my Galaxy 10, and I can confirm it works on both. If you don’t have Android 10, MIUI, or One UI, you’ll have to wait for Facebook to add a toggle in the settings on Instagram.
