Why is it important to keep a check on "App permissions"?
Once you install an app, you should keep a check on the permissions that you give to that application. "App Permissions" is a section in your phone's settings and is pretty self-explanatory. This basically lets you decide what an app is allowed to use or do on a smartphone. For example, if you deny permission to location, then the app won't be able to keep a track of your visits.
When you first open an app after installing it, you are asked to give certain permissions and some users blindly accept them. The apps then take advantage of this and get access to those features that aren't required to run them, purely with an intention to steal or collect your personal data without your authorisation. Keeping a track of permissions will also help keep your phone and data safe from malicious apps too.
For example, Truecaller has permissions for SMS and Camera, which is not really required. This basically means that the app is able to read your important bank messages, which some of you might not be comfortable with. Similarly, Outlook doesn't have access to any permission, but you will notice that Gmail has access to both Camera and Microphone, among others.
How to modify App permissions?
You will find this in your phone's settings > Apps and Notifications > App Permissions. (This is for OnePlus smartphones, but the process is mostly similar for other phones too. One can simply search for "App Permissions" on the search bar.) Here, you will be able to check permissions for all the apps. Alternatively, you can long-press on an app, tap on "App info," and tap again on Permissions. You can repeat this processor for every app.
Google has offered an important privacy feature with Android 12 - Privacy Dashboard. This lets you check all the permissions that have been used by apps in the past 24 hours. You also get to know the number of times as well as the names of the apps. So, if you are suspicious about anything, then you can modify permissions. Those who have Android 12 can also change location settings for apps. If you don't want an app to access your precise location, then you can turn off this option. Your device will then only approximate location for apps like Weather.
Here's a look at a list of app permissions and what they do when they are enabled for an app.
