The first time we run an app on an Android device normally he usually asks us to give him access to certain sections of the system (camera, contacts, phone etc.). It's the typical pop-up window that sometimes we don't pay much attention to. If we have granted the permissions without paying much attention, or if we simply have suspicions that an app has too many privileges, we can always revoke them.
How to manage application permissions on Android
If I have an app installed to recover deleted photos from WhatsApp, for example, it is logical that the application asks me for access to the internal memory of the phone. Of course, if you ask me for access to my contact list or SMS, I would think that you are exceeding your intentions and that you are trying to collect data behind my back, or even worse.For example, it is normal for a photo editor like Pixlr to need this type of access. Everything OK.
To fix this, we can control the permissions assigned to applications from the Android settings menu:
- We are going to "Settings -> Applications”.
- In the list of applications click on the cogwheel located on the upper right side.
- We select "Application permissions”.
At this point, we will find a list of types of authorizations: storage permissions, calendar, contacts, camera, microphone, SMS, body sensors, phone, location and additional permissions. We just have to click on each of them to see which apps have access to that specific section of the terminal.
Finally, we canactivate or deactivate the corresponding tab to each of the apps to give or deny the access in question.
In this way we control the management of the permissions held by the apps that we have installed on the device, and we make sure that none of them pee out of the pot. It is not something we should do very often, but it is advisable to take a look from time to time to make sure that everything is still in order.
Management of permissions and accesses in Android Oreo
If we have a more recent mobile with Android 8.0, these types of permissions are managed differently. Instead of entering Applications and clicking on the gear that appears in the upper margin, we must go to «Settings -> Applications and notifications»And scroll to the section«Permissions in applications«.
How to manage application permissions individually
In the most current devices the system also allows us to manage all the permissions granted to the applications individually.
- We go to «Settings -> Applications and notifications».
- We select the application whose permissions we want to edit.
- Click on "Permissions".
From here we can see all the specific permissions an app has specifically, and give or remove the corresponding privileges as we see fit (storage permissions, contacts, camera, microphone, SMS, phone and location).
How to give or remove Internet access permissions to certain applications
These steps that we can do from the settings of our Android phone are very good, but at least until now, they do not allow us to control the use of data made by the applications.
Anyway, this is something that Google has already thought about, and that is why it has developed the application Datally, a tool with which we can control the expenditure of megabytes made by each of the applications that we have installed, and restrict access to them individually.In this image, the Chrome browser and Google Maps have restricted Internet access (closed padlock)
We can download Datally for free directly from the Play Store:Download QR-Code Datally: data saving app by Google Developer: Google LLC Price: Free
As you can see, a very useful complement, and essential if we want to have more control in the management of resources on our Android device.You have Telegram installed? Receive the best post of each day on our channel. Or if you prefer, find out everything from our Facebook page.
