Many apps now offer an optional or mandatory Dark Mode setting to avoid this. It's easy to do on iPhone, and a little more complicated (though it's still technically possible) on Android .
How to Enable Snapchat Dark Mode on iPhone
Snapchat has a Dark Mode available for iPhone users. To take advantage of it, first, go to your profile and click on the icon on the top left. Next, select Settings, using the little "gear" as the icon. Then scroll right down to the "My" Account section. There you will find a panel that says App Appearance and tap on it. From there, you have three options.
You can tap Always Light, which means Snapchat will display the light theme permanently. Users can also select Always Dark, which initiates persistent Dark Mode. Another option is Match System, which will keep Snapchat in touch with your iPhone's system settings. So, if you enable system-wide Dark Mode on your iPhone, Snapchat will match it. And if you turn off that setting for your iPhone, Snapchat will follow suit too.
Sapchat Dark Mode for Android
Android is currently testing Dark Mode, but hasn't released it to the general public yet. That means you have to enable the Developer Mode version of Android. It gives you access to some features that are not available to regular users. Go to Android settings, then head to Display.
Next, select Dark Mode, which activates the black theme on all Androids. Then go back to Settings and select About Phone �" near the bottom. Go to Software Information, then tap Build Number a few times. This will allow you to enable Developer Mode.
Next, go to Settings and select the new Developer Options, where you will find the Force Dark Mode panel. Switch it to the "on" position, and you'll find that Snapchat Dark Mode on Android & iPhone.
