Google’s goal lately is to improve Android privacy and security, and Samsung has always been a leader in these areas. As a result, One UI 3.0, which is based on Android 11, is the most secure operating system version ever on Galaxy phones thanks to minor changes and new features.
A major focus of One UI 3.0 are app permissions with the aim of giving users more control over their personal data. In addition, the latest version of Android has new protection features that run in the background. These changes and APIs will better protect your Galaxy smartphone without you having to do anything. Here are some of the most notable ways One UI 3.0 makes Galaxy devices more secure.
. Temporary permissions
You can now temporarily grant apps access to a permission. The camera, microphone, and location have a new option in the permission prompt: “This time only.” If you select this option, the app is granted one-time access. However, once it is closed, it will have to request authorization again in order to be able to use it again.
2. Access to the background location must be granted manually
In One UI 3.0, “Always Allow” is no longer an option in the permission prompt when an app asks for access to your location. In previous versions this was used to give access to the background location.
Apps can still get this permission just not with a single tap. You can either go to “Permission Manager” in Settings to manually grant access to the background location, or apps can add an extra button to the permission prompt that will take you to the “System Settings” menu where you can then grant access. Definitely an improvement for casual users who don’t understand the implications of these settings.
3. Automatic reset permissions
If an app has not been used for several months in One UI 3.0, its permissions can be automatically revoked. If you use the new “Remove permissions when app is not in use” switch on an app’s permissions page (the app must be Android 11 targeted to see this toggle), any granted permissions will be changed to Deny.
4. Protection against app queries
In previous versions of One UI, any app installed on your device could ask the system for the full list of other apps installed on your device. That way apps could check if you had a required second app or an app they didn’t want to interact with.
However, this information has been misused by some apps as a method of tracking users and collecting data. This policy was changed in One UI 3.0. Apps that request a list of installed apps will see a filtered list of installed apps by default. If the information is not in this list, you can query certain items.
5. Repeated authorization requests are automatically blocked
Instead of receiving the same permission request for a permission you deny, One UI 3.0 treats the user interface as “Don’t ask again” if you deny a permission twice. You will no longer be asked to enter the authorization, but you can activate it manually in the system settings.
6. Spam protection
The FCC has an authentication tool called STIR / SHAKEN that verifies phone numbers. They have ordered all US airlines to implement this system on their network to combat robocalls and spam.
In One UI 3.0, call review apps can STIR / SHAKEN access review status and use that information to improve unwanted call blocking.
7. Scoped Storage in full effect
Scooped Storage was first implemented in One UI 2.0 and has changed the way apps interact with the file system. App access was limited to just a few folders in internal storage so apps couldn’t see your other files. Too many apps got corrupted, however, so Google had to create a temporary workaround.
In One UI 3.0, apps must now use scooped storage. One UI 3.0 has a new “Access to All Files” permission for file managers, with which you can work as in previous versions. However, the app must meet certain requirements to qualify for this entitlement. All other apps are limited to “media access only”.
8. No more assignable standard camera
In One UI 3.0, users can no longer set a default camera. You can still use third-party camera apps and the camera functions built into apps like Snapchat. However, when an app requests the use of a camera app, it must use the phone’s pre-installed camera app. This was done to prevent apps from stealing your location by reading geotags on your pictures.
9. Disable automatic USB audio routing
There is a new entry in the developer options called “Disable USB audio routing”. When you connect an audio device to your phone via USB, the automatic routing of audio to that device is disabled.
10. Better protection through tracking location
If an app needs to access antenna properties to improve tracking accuracy, the One UI 3.0 has some limitations to protect your privacy. First, the API that the app uses to access this information is only specific to the device model. Second, the user must give the app location permission to collect this information.
