Using Instagram Dark Mode on Android phones
This is not a complicated process, but it may be a while until your Android phone has this feature. Why? Well, you need to have Android 10, the latest Android OS, to access Dark Mode on your phone.
Check if you already have Android 10 or if you can upgrade to it. To see if there is an upgrade available, go to Settings > System > System Update.
Once you've updated to Android 10, turn on your Dark Mode by going to Settings > Display > Dark Theme.
Open the Instagram app.
You can also turn on Dark Mode via Battery Saving Mode by going to Settings > Battery > Battery Saver. The two are connected now, as Dark Mode saves battery life, so if you switch on Battery Saver, you'll automatically go to Dark Mode.
Dark Mode will be active in your Instagram app when you have it turned on in your phone settings, and you'll be able to scroll with it until you turn of Dark Mode on your phone.
