MIUI started off a custom ROM initially before Xiaomi started shipping it on their smartphones including the Mi 3. For an OEM firmware, MIUI packs in a plethora of customization options, which are usually found in custom ROMs. One such feature in MIUI is Permissions Manager, which is found only in certain custom ROMs.
As the name suggests, Permissions Manager allows users to control the permission of the installed apps on their handset. They can set the OS to either prompt them whenever an app requests for a new permission, or deny it completely altogether.
If you have recently got your hands on the Xiaomi Mi 3 or any other device running MIUI, follow the steps below to find out how to use Permissions Manager and to make the most of it.
Step 1: Head over to Security -> Permission. Enable Permission Manager, if it is not already enabled.
Step 2: Then, tap the Manage App Permissions option, where MIUI will categorize all apps according to the permissions requested by them. This comes in handy if you want to check, for example, all the apps that are accessing your contacts and reading your messages.
You can then individually select the app and then either set the OS to prompt you when it requests that permission, or deny it altogether.
Step 3: If you want to see the permissions used on a per-app basis, swipe over to the Apps tab. You can then tap on an app’s name and see all the permissions accessed by it. As in the previous step then, you can deny the app from using that permission or set the OS to prompt you when it requests that permission.
With certain Android apps stealing user data in the background, features like Permission Manager should ship as default on all Android devices.
