Samsung One UI 4.0 With Android 12: Best Features 

Google's Material You 

We just mentioned how Samsung decided to go with Google’s Material You design and we love it. You can pick system colors based on your phone’s wallpaper. Although it doesn’t work as well as it does on Pixel phones, it’s as close as you can get. It’s not all bad; for example, Samsung’s One UI 4.0 doesn’t push the gigantic brightness slider that we can see on Google Pixel’s Android 12 update. 


Android 12 is taking privacy seriously and so is Samsung. We have already seen their Knox security in many smartphones and with One UI 4.0 on top of Android 12, they are taking things to the next step. 

  • Much like iOS 15, a green dot will appear on the top right corner of your smartphone whenever any app uses your microphone or camera. There is also a toggle in the quick panel where you can block camera and mic access temporarily for all apps.
  • Under a new feature called Permission Usage History, you can view all apps that are using sensitive information such as camera, microphone, location and so on. 
  • For apps that demand your exact location for no particular reason, you can allow them access only to an approximate location/area of where you are. You do not have to give them your exact pinpoint location. 
  • Whenever you copy sensitive information to your clipboards such as password, OTP, or credit card number, you can choose to be notified whenever any app is accessing your copied content from the clipboard to their own app.

Home Screen & Lock Screen 

  • Home screen widgets have a fresh new look which is not just aesthetically pleasing but also provides more useful information in the same space. The new dual clock widget for instance shows different background colors for each city depending on what time of day it is. 
  • You may also choose to receive personalized widget recommendations so you can get the most out of your Samsung One UI 4.0 smartphone. 

More than the Home Screen, the Lock Screen has some sweet upgrades that improve the experience of using your Samsung device without even unlocking it. 

  • Different music streaming apps such as Spotify, Amazon Music, or YouTube Music will have different custom layouts on the lock screen. You can seamlessly switch between different audio outputs such as headphones, speakers, and so on. 
  • How many of you use a voice recorder, a notes app, or just WhatsApp voice messages for recording audio? With Android 12 onboard One UI 4.0, you can do this right from the lock screen without even unlocking your device. 

A subpart of the lock screen, the Always On Display too has some updates. 

  • You can now set your AOD to turn on only when you get a notification instead of having it on all the time. That will definitely save some battery. Secondly, more new animated stickers will be available for the best Android 12 customization experience.

Camera & Gallery App

The overall camera layout and user-friendliness have been improved in One UI 4.0 beta with Android 12. For example, you can start recording as soon as you tap the record button without waiting for it to start when you release it. In the photo mode, you can finally touch and hold the shutter button to start recording instantly instead of having to switch to video mode. 

In the new Android 12 gallery on Samsung phones, you can revert to the original picture anytime even after all edits and saving it. Samsung also allowed users to go one step further by giving them edit access to the date, time, and location of any picture/video. Don’t know what we’ll use it for, but how cool is that?

  • With large screen sizes especially on the Samsung fold and flip phones, you can multitask with ease-pin apps, easily resize picture-in-picture mode, and zoom in wherever necessary. 
  • In the in-built Photo Editor, you can cut out objects from a picture such as a face, pets, and other things to easily paste them into another one.
