One UI 4.0 Update Release Date

Google pushed the source code of Android 12 to the Android Open Source Project (AOSP) on October 4th. However, the Android 12 roll-out for Google Pixel devices has yet to begin.

Samsung, on the other hand, is running the Android 12-based One UI 4.0 beta programme and the second beta is out for certain Galaxy devices. But at present, there is no telling when Samsung will release the final version of One UI 4.0. If we take notes from last year’s One UI 3.0 release, we can expect Samsung to launch the One UI 4.0 in December, or at least by the end of the year.

One UI 4.0 Top Features

Here are some of the top features that are expected to be a part of the upcoming One UI 4.0 update.

UI enhancements

As with every One UI upgrade, Samsung has again added some design changes to the UI for enhanced user experience. First of all, the overall UI is now smoother and faster.

The widget section is now stacked vertically, taking direct inspiration from the Android 12’s widget look. You can now apply dark mode to the wallpaper in case you want a consistent look when the device is set to a dark theme. Also, there is a new charging animation.

In the home screen settings, there is a new Add media to home page option where you can choose between adding a Google discover page or Samsung Free.

Color Themes

Similar to Android 12, Samsung has introduced color themes in One UI 4.0 in which the OS extracts color pallets from the wallpaper. You can choose between the color themes that will apply to the entire UI. However, the feature is still in beta stage and doesn’t apply the color scheme as effectively as you would see in Android 12. Color Theme is available in the Wallpaper section which you can find by long-pressing on the home screen

New Privacy Features

Android 12 has several new privacy features, and Samsung is trying to bring all of them to One UI 4.0.

To start off, there is a new permission history under the privacy settings where you can see app usage permissions over the last 24 hours. You can go back as long as seven days for sensitive permissions including Camera, Location and Microphone. 

Speaking of sensitive permissions, the One UI 4.0 also features Android 12 privacy indicators. If an app tries to access your camera or microphone, you will immediately see an indicator in the top right corner of the screen.

Under privacy settings, there are toggle buttons for camera and microphone access. Once disabled, all apps with access to the camera or microphone will have their permission revoked. The same toggles are available in Quick settings as well.

Also, you now have the ability to give an approximate location to apps. The toggle is available with location permission for each app.

Extra Dim

Straight out of Android 12, the One UI 4.0 has a new feature called, “Extra Dim.” As the name suggests, you can dim the screen beyond the minimum screen brightness.

The feature is available in One UI accessibility settings, where you can turn it on and change its intensity. You can also toggle it from the Quick settings menu.

Multi-Window Support 

Under Advanced Features, you will now find the Force multi-window option. As the name suggests, it allows you to force split-screen view and pop-up view on apps that do not support the same.

RAM Plus

Virtual RAM feature the is getting popular, and now Samsung is adding the feature to the Galaxy phones in the One UI 4.0. As the name suggests, the feature uses external storage and uses it as virtual RAM to improve the overall app performance. Currently, we don’t know which smartphones will get the feature.

Lock Screen and Always-On Display

The Android 12 One UI 4.0 has brought a few changes to the lock screen as well. There are new media controls when playing music. You can change the audio output right from the lock screen. Also, you will see customized controls depending on which music app you’re using.

You can now add a recorder widget to the lock screen that allows you to create voice memos without unlocking your phone.

Coming to Always-on display or AOD, there are new animation stickers. You can set AOD to only awake when you receive a notification.

Camera and Gallery

The One UI 4.0 introduces a number of changes to the camera app as well as the gallery app. Now, you can touch and hold the shutter button to start recording a video in Photo mode. You can also drag your finger to the lock icon to keep recording.

In video mode, you can start recording as soon as you touch the record button. While scanning a document, you can now zoom in to edit the document.

Similar to Google Photos, you can revert an image in the Gallery app to its original version even after they are saved. Also, you can now edit the date, time and location of a picture or a video.

Samsung Keyboard

The latest changelog reveals that Samsung will be bringing in a new Samsung Keyboard with the One UI 4.0 update. The update will allow users to get emojis, GIFs, and stickers directly from the keyboard with a single button. One can also combine two emojis and add animation with the keyboard application. It also brings in a new writing assistant, which will be powered by Grammarly.
