You may not know, Facebook has a hidden Dark Mode feature on iPhone, but you need to manually set it up and tweak it to Facebook’s file system to activate it. The Dark Mode feature will make your eyes softer when using Facebook at night. Especially the mysterious black color always makes people more interested than the traditional white of Facebook. In this article, AnonyViet will guide you how to activate Facebook Dark Mode for Jailbroken iPhone.

Instructions to install Facebook Dark Mode for Jailbroken iPhone

Note that iPhone needs to be jailbroken before doing so. If you do not know how to jailbreak, see the instructions at Jailbreak with unc0ver 5.0 in all current iPhone Firmware.

The advantage of activating this Facebook Dark Mode feature is that the owner is from Facebook, not using other sources. Therefore, the interface and dark colors will be easier to see than other tweaks. When you enable this feature, you will be able to experience this feature before Facebook’s Dark Mode feature officially launches.

Install the necessary tweaks:

• Filza
• Icleaner
• File Dark Mode (Download)

Download File Dark Mode, then use Filza to copy the file group.com.facebook.Facebook.plist by path:

/var/mobile/Containers/Shared/AppGroup/Facebook/Library/Preferences

Next you need to perform the steps below to avoid losing Dark Mode when exiting multitasking or respringing iPhone:

• Install name tweak: Terminal at source: https://repo.chariz.io/
• Install Tweak Name: NewTerm (IOS 10-13)
• Install name tweak: file-cmds

When the installation is done, remember Respring machine again.

Next:

Go to the app NewTerm:

Step 1: import su —> enter

Step 2: will ask for password —> enter alpine press enter (when entering it will not display anything, just press enter after entering).

If successful, you will see a message root#

Step 3: Next enter the command:

chflags schg /var/mobile/Containers/Shared/AppGroup/77837032-CE1B-4563-B029-059881EAA129/Library/Preferences/group.com.facebook.Facebook.plist

Attention The path of each machine will be different in Filza as instructed above

Eg: /var/monbile/Containers/Shared/AppGroup/Facebook/Library/Preferences

Then ../Facebook/.. is the code 77837032-CE1B-4563-B029-059881EAA129 because each machine is a different code

You can copy it at Filza to save a lot of writing.

If Facebook is open, turn off Facebook and open it again. Then enter Settings -> Settings & Privacy will see more features Dark mode.

** If you find the above steps complicated, you can install tweak FacebookDark (system) at the source repo: https://repo.thuthuatjb.com/

You can now use Facebook Dark Mode permanently. If you update Facebook to the new version, you need to do the operation from the beginning.

Turning on Dark mode when it is dark will help protect eyes when using the phone too much. Dark Mode is a feature that changes the user interface to a dark background. This is especially good for your eyes at night when the light is low. So, I will show you how to automatically turn on Dark mode when it gets dark on Android devices.

System-wide Dark Mode has been available on Android since version 10 of Android and is available on all following versions. Part “the whole system” This means that Dark mode will apply to the entire operating system, not just individual applications. Therefore, I can turn it on everywhere with a simple toggle, or better yet, set it on a schedule.

While system-wide Dark Mode is available for all Android 10 or newer devices, the process to enable Dark mode at night may vary depending on the phone or manufacturer. I will guide on the interface of Google Pixel and Samsung Galaxy devices.

How to turn on Dark mode when it’s dark on Android

First, swipe down from the top of the screen (once or twice, depending on your device manufacturer) and tap the gear icon to open the “Settings” menu.

Next, go to the “Display” setting.

At this point, the options and interfaces will vary depending on the manufacturer of the Android device. Most manufacturers name it “Dark Mode” or “Dark Theme”, but change it to “Night Mode”.

To schedule Dark mode, please click “Dark Theme” on phones like Google Pixel.

On Samsung Galaxy devices it is “Dark Mode Settings”.

Next, tap on “Schedule”.

We can now select “Turns on From Sunset to Sunrise” to enable Dark Mode when it gets dark on Google Pixel.

On Samsung phones, this setting is simply called “Sunset to Sunrise”.

That’s it, for apps to follow the automatic theme change, you’ll need to go to the “Theme” setting in the app. If the app supports system-wide Dark Mode, you’ll see an option to have the theme follow the system.

When it gets dark, all apps that follow the system settings will be switched to dark mode. This is a great way to protect your eyes At night.

You may already be familiar with media queries. They are being widely used to make responsive websites. The width and height properties contain the dimensions of the screen. You will then use CSS to render different layouts at different screen sizes.

Media query prefers-color-scheme works in a similar way. Users can configure their operating system to use light or dark mode. Prefers-color-scheme contains that value. The value is light or dark, although the W3C spec says it may support other values ​​in the future like sepia. We will specify different values ​​of CSS variables for both modes and let the user’s operating system decide.

Some simple CSS tricks for dark mode

Using media queries prefers-color-scheme

Two values ​​of media query prefers-color-scheme to be:

/* Light mode */
@media (prefers-color-scheme: light) {
   :root {
       --body-bg: #FFFFFF;
       --body-color: #000000;
   }
}

/* Dark mode */
@media (prefers-color-scheme: dark) {
   :root {
       --body-bg: #000000;
       --body-color: #FFFFFF;
   }
}

In the above CSS code, –body-bg and –body-color are CSS variables. As you can see, they contain different values ​​for both modes. In light mode, I set a white background with black text. In dark mode, I set the background to black with white text.

Since the W3C may introduce values ​​in the future, it makes sense to convert this CSS to a boolean.

/* Light mode */
:root {
   --body-bg: #FFFFFF;
   --body-color: #000000;
}

/* Dark mode */
@media (prefers-color-scheme: dark) {
   :root {
       --body-bg: #000000;
       --body-color: #FFFFFF;
   }
}

In the above code, I am defining light mode by default and converting it to dark mode if the media query is dark (i.e. the user uses dark mode on the operating system). This way, any future values ​​added to the media query will set light mode by default.

Using CSS variables

Now that we have different values ​​for different themes, we will use them to style the page.

body {
   background: var(--body-bg);
   color: var(--body-color);
}

Syntax var() is how CSS uses variables. In the above code, I am saying to set the background to the value of –body-bg and set the color to the value of –body-color. Note that the values ​​of these variables come from the media query. Means background and background colors based on operating system settings.

This is the true power of media queries: Deliver a consistent user experience from the operating system to the website.

If you visit findmymastodon.com and switch the operating system theme, you will see the website switch from one theme to another.

Conclusion

Note that the use of prefers-color-scheme It’s no different than using a regular programming language. We define variables whose values ​​change based on some logic. And those variables are used for further operations.

The ability to allow your site to adapt to a user-selected theme is a great feature. And it further blurs the line between desktop and web for the benefit of users. Latest browser versions supported prefers-color-schemeso you can start trying it out today.

Change wallpaper when it’s light or dark? Night and day mode, is one of Android’s best recent features. What if your wallpaper can also be changed to sync? I will guide you to do that in this article.

Dark mode works slightly differently depending on the device, but typically it changes the color of Quick Settings, Settings app, and other menus. However, if you use a light-colored wallpaper, it will still be blinding. Now you need to use an application called “Dark Light Mode Scheduler”.

The principle behind this application is very simple. You choose a background image for light mode and you choose a wallpaper for dark mode. Whenever the mode switches, whether it’s done manually or automatically, the background image changes accordingly. You can learn how to enable dark mode in good weather on Android here.

How to automatically change wallpaper in dark and light mode on Android

Download the app first Dark Light Mode Scheduler from the Google Play Store on your Android phone. Launch the app and toggle the switch at the top of the screen to let the app automatically change the wallpaper.

Next, select “Schedule” and choose how you want the wallpaper to change. You can set it according to system settings or create a separate schedule.

Now we can choose the wallpaper for the home screen. Tap each “Light Mode” and “Dark Mode” image to select a photo from your device. You will need to give the app permission to access the storage on your device.

Once you’ve chosen a wallpaper for your home screen, you can do the same thing for your lock screen.

That’s all you need to do. The wallpaper will automatically change to match the system settings or the schedule you’ve created. Now you can use bright wallpapers during the day and don’t have to worry about glare at night :v.
