Modern mobile devices store a colossal amount of personal information, from correspondence in instant messengers to real-time geolocation. Many users do not even suspect that the games and utilities they install often request excessive rights that go far beyond the scope of their functionality. For example, a simple flashlight may require access to your contacts, and a calculator may require access to your geolocation, which is a clear violation of the logic of the software.
Control over these requests is not just a matter of paranoia, but a basic digital hygiene skill that every smartphone owner needs to master. By limiting access, you not only protect your data from leaks, but also extend the battery life of the device, since background processes stop constantly polling sensors. In this article, we will analyze in detail all the available methods for managing access rights in the operating system Android.
Basic principles of the permissions system in Android
Starting with Android 6.0 Marshmallow, Google introduced a runtime permissions model that radically changed its approach to security. Now rights are issued not at the time of installation of the application, but at the time of the first call to a specific function, which gives the user complete control over the situation. The system groups accesses into categories, such as Camera, Microphone, Geolocation and Contact, allowing you to flexibly configure each of them separately.
It is important to understand that some permissions are critical for the operation of the app, and blocking them can lead to the inoperability of individual functions or the entire application. For example, if you deny your navigator access to GPS, it will physically not be able to build a route, and blocking the microphone will make voice calls in instant messengers impossible. However, there are so-called “dangerous permissions” that require special attention when issuing.
- 🔒 Normal permissions —accesses, such as access to the Internet or setting an alarm clock, that the system issues automatically without a request.
- ⚠️ Dangerous permissions —access to personal data, camera, microphone and location, requiring explicit confirmation user.
- 🛡️ Special permissions —rights to overlay other windows or change system settings that are hidden in deep menus.
It is worth noting that smartphone manufacturers often modify the settings interface by adding their own skins on top of the clean one. Android. This means that the names of menu items may differ slightly on devices Samsung, Xiaomi or Huawei, but the operating logic remains the same for the entire ecosystem.
⚠️ Attention: The security settings interface may change with the release of new versions of the operating system. If you do not find the described item, use the search inside the settings menu of your device by entering the keyword "Permissions".
Global access control through system settings
The most reliable way to control which applications have access to your data is to use the global permission management menu. Here you can see a list of all apps that have access to a specific function and disable them en masse or selectively. To go to this section, you need to open Settings, then select Applications or Applications and notifications, then find the tab Permissions or Permission manager.
The list that opens will contain all categories of sensors and data that apps can request access to. By clicking on any of them, for example, Camera, you will see a complete list of applications that can use it. Here you can also switch the toggle switch to the “Off” position for any suspicious software, instantly limiting its capabilities.
☑️ Checking the security of your smartphone
Particular attention should be paid to sections Microphone and Camera, since It is through them that surveillance most often occurs. If you find that a simple photo editor or solitaire game has access to the microphone, this is a clear signal to immediately disable this right. It is also useful to periodically check access to Contacts and SMS, since this data is of the greatest value to attackers.
⚠️ Attention: Disabling system applications (marked with the Android robot icon) can lead to unstable operation of the operating system. Be careful when limiting rights for Google services or system components.
Individually setting rights for each application
Often a situation arises when you need to fine-tune rights for a specific app without affecting others. To do this, go to the menu Settings > Applications and select the application you are interested in from the list. Inside the app card, find the item Permissions, where a detailed list of all requests will be presented with the ability to change them.
In this menu you will see three main statuses for each item: “Allowed”, “Forbidden” and, in new versions of Android, “Ask” or “Only when using”. Selecting the option "Only when in use" is the safest and recommended for most cases, since the application will only be able to access the sensor when it is open on the screen.
What is "Single Line Resolution"?
Android 11 and later introduced the feature issuing permission for only one session. If you select this option, the application will only have access to the camera or microphone until it is closed, and the request will be repeated the next time it is launched.
Some applications may aggressively request permissions each time they are launched if they need them for basic functionality. If you deny access to a key function, the app may begin to work incorrectly or constantly generate errors. In such cases, it is worth assessing the feasibility of using such software or looking for a more respectful analogue.
- 📱 Social networks - usually require access to the camera, microphone and gallery to download content.
- 🗺️ Navigation - critically depends on the exact geo-position, background access can be useful for building a route.
- 🛒 Stores and deliveries —require geolocation to determine the address, but they do not need access to contacts.
Special features and advanced settings
In addition to standard permissions, Android has a special category capabilities that are often used by malware to intercept control. Accessibility allows applications to read text on the screen, track keystrokes, and even perform actions on behalf of the user. This section is located along the path Special Features (Accessibility) allows applications to read text on the screen, track keystrokes, and even perform actions on behalf of the user. This section is located along the way Settings > Special Features (or Special Features).
The installation control for unknown applications is also located here, which allows apps to install other apps without user interaction. It is recommended to keep this switch turned off for all applications except trusted stores, such as Google Play or Galaxy Store. Enabling this right for a browser or file manager creates a huge security hole.
| Permission type | Security risk | Recommended status |
|---|---|---|
| Screen access | High (password interception) | Forbidden |
| Installing applications | Critical (viruses) | Forbidden |
| Device administrator | High (blocking) | Only for antiviruses |
| Access to notifications | Medium (theft of 2FA codes) | Forbidden |
Access to notifications deserves special attention. users don’t think twice about it, but by allowing an application to read notifications, you actually give it access to two-factor authentication codes from bank SMS and instant messengers. Never give access to read notifications to applications that are not launchers or smartwatches.
Use the "Access indicator" feature (the green dot in the corner of the screen) to see in real time which application is using the camera or microphone right now.
Temporary permissions and mode "Not disturb"
In modern versions of Android, starting from 11th, a temporary permissions function has appeared. When you select the "Only in this case" option when requesting permissions, the application only has access to the function for one session. The next time you start, the system will ask for confirmation again, which is ideal for rarely used apps.
It is also possible to automatically reset permissions for applications that you have not used for a long time. This feature is activated in the general privacy settings and helps keep your system clean. If you installed an application, used it once and forgot, after a few months it will automatically lose all previously granted rights.
Automatically resetting unused permissions is the best protection against "sleeping" threats when a forgotten application is updated and begins to collect data.
Do not disturb mode also affects the operation of some applications, limiting their ability to publish sounds or pop up on the screen, although this does not directly prohibit access to the sensors. Combining these tools allows you to create a flexible security system adapted to your style of smartphone use.
Frequently asked questions (FAQ)
What happens if I turn off all permissions for a system application?
This can lead to serious malfunctions in the operating system: notifications will stop coming, calls may not work or the Internet. System components such as Google Play Services or Phonerequire basic rights for the smartphone to function. It is recommended not to touch system applications unless you know exactly what they are responsible for.
Can the application work without access to the Internet?
Yes, many applications (calculator, voice recorder, offline maps) can function without access to the network. However, most modern apps will lose some functionality: there will be no advertising (which is a plus), but news, synchronization or updates will not load. You can disable the Internet in the "Mobile data and Wi-Fi" setting in the permissions menu.
How to find out which application recently used the camera?
Starting with Android 12, a green indicator appears in the notification shade (quick access panel) when using the camera or microphone. If you pull or tap on this indicator, the system will show the exact time and name of the application that accessed the sensor.
Is it safe to use third-party permission managers?
Using third-party applications to manage rights is often redundant, since Android's built-in tools are quite powerful. Moreover, third-party managers themselves can request excess rights for their work. It is better to trust the native security settings from Google and the device manufacturer.
Why were some permissions reset after an Android update?
With major updates to the operating system (for example, from Android 12 to 13), the security policy may change, and the system automatically resets permissions for applications that have not been used for a long time, or for those whose requests are considered more risky. This is normal behavior aimed at protecting your data.
