Phone application’s permissions
When you install apps on your phone, they ask for “permissions” on the phone. Such as: access to contacts – access to device memory – access to geographic location – access to the camera of the phone – access to the call log … And many other permissions.
Google and through the application “Google Store” obliges the owners of the applications to disclose the permissions required by the application, thus the permissions required by the application appear when installing the application and can be reviewed before installation.
For applications on IOS phones, permissions are required after the application is installed
What is the purpose of the permissions requested by apps?
Permissions allow the application to access the options and information that allow it to do its job. Example: When installing an application for written and voice communication (such as Whatsapp, Signal, Wire or Telegram), these applications need access to the keyboard (so that we can write messages within the application). Need access to the microphone (so we can make a voice call or send voice messages from within the app). Need access to the camera (so we can make a video call or shoot from within the app). Need access to contacts (so we can identify contacts and communicate with them through the application).
Or when you install an app to edit images, the app needs access to the photo studio and device memory (so we can select and save the image) and some need access to the keyboard (to add text to the images).
Do apps require only the permissions they need?
No! A number of applications will ask for permissions that are not needed for the application.
Example: An app that controls the device’s flash light
It is noted that the application requests access to the geographical location, access to the camera and to take pictures, and full access to the telephone network.
They are unjustified permissions for the application only needs access to the device’s flash light.
Some applications request unjustified permissions. Its purpose is to gather information for several reasons, including propaganda purposes. And some applications will have a sly purpose.
In Android versions prior to 6.0, it was not available to control permissions for all apps, and we had to use an app that helps us revoke the permissions of the apps. As of version 6.0 users can control the permissions requested by the applications (cancel and activate permissions for each application). As with IOS devices (iPhone).
Although Google forces the owners of the applications to reveal the permissions required by the application, some applications were able to bypass the Android operating system protocol and get the user’s data without asking for permissions details in the link here
For this and other reasons, when you download an app on your phone you should:
- Download apps from trusted app stores like the Google Play Store. Do not download apps from suspicious stores or sites without knowing their source.
- Make sure from the identity and credibility of the developer of the application … Also you should not install unknown applications.
- Read the reviews well to learn more about the application, try to search for reviews that address the topics of privacy and security. Do not download and install applications with negative reviews regarding privacy and security.
- Review the permissions requested by the app well. Do not install any application that requires more permissions than it needs to accomplish its work, or that requests permissions that may be a risk to your privacy and security.
