One of Facebook’s most popular settings, “dark mode”, mysteriously disappeared from the iPhone version of the app over the weekend, leaving users perplexed.
According to 9to5Mac, the “dark mode” option on iOS disappeared without any explanation. The setting allows you to change the design of the app from white to black to reduce eye strain and provide a more comfortable viewing experience for users.
The Facebook app on iOS will no longer adjust based on a user’s system-wide “dark mode” settings, nor can it be enabled or toggled on the app itself.
Facebook has yet to acknowledge the issue or provide a timeline for a fix.

Despite the fact that the iPhone experts at 9to5Mac believe the change isn’t deliberate on Facebook’s part, app users have still taken to social media to complain about it.
“I realize this is a huge first world problem, but having no dark mode on the iOS version of Facebook really sucks when your whole phone is on dark mode,” wrote journalist Meghin. Moore on Twitter.
“I hope whoever did these steps exclusively on Lego for a year,” wrote another.

Although the iPhone does not currently have dark mode for Facebook, it does have a number of features that work even when the battery is drained.
The “Find My” app can still be used for several hours after an iPhone runs out of juice, so if someone steals your device and turns it off, you can still find it.
Contactless payments via iPhone’s “express mode” also continue to work without a battery, allowing you to continue shopping or unlock your car’s smart lock.
