How to reset permissions for all apps on Android

If you've been installing apps on your phone for a while, you've probably granted more permissions than you intended without even realizing it . Camera, microphone, location, contacts… in the end, half your phone is accessible to apps you don't even use. The good news is that Android is increasingly offering more options to review and reset permissions for all your apps almost at once, without having to go through them one by one blindly.

In this comprehensive guide, you'll learn how permissions work on Android, the different types available, and how to reset them (revoke, adjust, or let the system remove them automatically), both app by app and by permission type. We'll also cover which permissions are more sensitive, what extra security options exist, and what you can do if you want to take even further security measures with specialized tools.

What are app permissions on Android and why do they matter?

App permissions are the system Android uses to allow each app to request access to sensitive areas of the phone : files, contacts, messages, camera, microphone, location, body sensors, etc. Without these permissions, many functions cannot work, but granting them indiscriminately can compromise your privacy and your phone's performance .

These days, almost all apps display an Android dialog box when they need access to something sensitive, and you decide whether to Allow, Deny, or limit that access . Furthermore, you can always go into Settings later and change what you've granted. This gives you much more control than in early versions of Android, where everything was accepted upon installation.

It is important to understand that some permissions are only requested when installing the app , while others are requested in real time, the first time the application tries to do something that requires them (for example, opening the camera to take a photo or accessing the location to show you a map).

Types of permissions in Android: installation, runtime, and special

Android categorizes permissions into several groups, based on the risk and type of access they provide. Understanding this classification helps you grasp the level of risk involved in granting each permission and why some are granted automatically while others require clear user notification.

Permissions at the time of installation

These are permissions that the system grants as soon as you install the application, without asking you during use . They have access to data or actions outside the app's "sandbox," but in theory, their impact on privacy and the system is very low.

Within this group, two main subtypes are distinguished: normal permissions and signing permissions . Both are considered relatively secure, but they function differently internally.

Normal permits

Normal permissions allow the app to perform actions that go slightly beyond its scope, but don't pose a significant risk to your privacy or affect other apps . The system marks these with the "normal" protection level and usually grants them automatically when you install the app.

Signature permissions

In this case, permission is only granted if the application is signed with the same certificate as the app or system that defined the permission. This model is used for highly privileged services, such as certain system services (for example, Autofill or the manufacturer's own VPN).

Many third-party apps cannot use certain signing permissions because Android reserves them for the system or for manufacturers/OEMs . The level of protection associated with these permissions is "signature" and is only available to very specific software.

Runtime permits (hazardous)

Runtime permissions, also called " dangerous permissions ", give access to highly sensitive data (contacts, SMS, location, etc.) or actions that significantly affect the system and other apps.

For these types of permissions, Android requires the app to request them while you're using it , before accessing the resource in question. You can't assume they're granted: the app must check if it has the permission and, if not, display the dialog box to request it.

Many of these permissions are considered access to " private user data ": GPS location, contact list, call history, photos, videos, etc. Furthermore, resources like the microphone and camera are considered especially sensitive, so the system usually displays messages and explanations to help the user better understand what's happening.

Special permissions

Special permissions control very specific operations, usually those with a high impact on the user experience . Only the Android platform itself or the manufacturers can define them, and they are used to protect things like drawing over other apps, modifying system settings, or activating special modes.

Much of this configuration is found in the "Special app access" section within the system settings. In this section, you can review which apps have certain advanced access privileges and change them if something seems wrong.

Permission groups

To simplify things for the user, Android logically groups related permissions into permission groups . For example, sending and receiving SMS messages can belong to the same group because they are related to text messages.

This means that when you grant a permission from one group, the other permissions within that same group are often granted automatically without additional dialog boxes, reducing the number of pop-up windows you see. However, Google warns that permissions can change groups without prior notice, so it's not advisable to assume that a permission will always remain in the same group.

Main permissions that apps request and what they entail

Your mobile phone is increasingly equipped with more sensors and features (GPS, accelerometer, heart rate monitor, multiple cameras, microphones, advanced Bluetooth…), and to that we must add the personal data: contacts, SMS, calendar, files . All of this is controlled through permissions that apps can request.

Reviewing these permissions carefully and restoring any unnecessary ones helps limit the risk of an app abusing the access you've granted it, either by consuming resources or jeopardizing your privacy.

List of usual permits

Some of the most common permissions you'll see are the following:

• Body sensorsThey read health data such as heart rate, steps, daily activity, or exercise parameters.
• Calendar: allows you to access, read and add events to your default calendar.
• Call logsThey consult and modify the device's call history.
• Camera: access to the camera to take photos and record video.
• Contacts: reading your contact list and, in some cases, modifying it.
• Location: use of GPS or nearby networks to know where you are.
• Microphone: real-time audio recording.
• Nearby Bluetooth devices: search and connection to nearby devices via Bluetooth.
• Contact Us: make and manage calls, in some cases read the network status.
• Physical activity: data about your movements (walking, running, cycling, step count, etc.).
• SMS: read and send traditional text messages.
• Storage / Multimedia Files: save and read photos, videos, documents or other files on the device.

Especially sensitive permits

There are certain permissions you should be particularly strict about. These include camera, microphone, SMS, contacts, location , and storage , because they can reveal a lot of information about you if they fall into the hands of malicious or overly nosy apps.

For example, granting unlimited camera access could allow an app to record images without your knowledge; microphone permission could capture audio in the background ; and sharing your SMS messages or contacts opens the door to unethical uses, such as data mining, targeted spam, or phishing attempts.

It's also important to pay attention to permissions for body sensors and physical activity . Although they may seem "innocent," they allow for the creation of health and habit profiles that, combined with other data, can be very valuable for highly aggressive advertising campaigns.

Best practices before restoring or granting permissions

Before you go crazy revoking permissions haphazardly, it's advisable to follow a few best practices suggested by the Android ecosystem itself . These will be useful both when granting new permissions and when restoring existing ones.

Request and maintain the minimum number of permits possible.

Whenever you use an app (whether developed by you or by a third party), try to ensure it only requests the permissions essential for the function the user wants to perform at that moment. Many tasks can be completed with alternatives that don't require access to sensitive data.

For example, to show relevant ads, the app doesn't necessarily need permission to read your contact list or your SMS messages . Similarly, to take a single photo, the app doesn't need access to all your external storage.

Link runtime permissions to specific actions

Ideally, requests for potentially dangerous permissions should be delayed until the user clicks a button or enters a section where they are truly needed . This way, the person understands the purpose of the permission.

For example, if an app allows sending audio messages, it doesn't make sense to request microphone access the first time the app is opened. It's more logical to wait until the user reaches the chat screen and taps "Send audio message" ; you can request permission right then.

Take care of the facilities and libraries you install

If you develop applications or use third-party tools, remember that any library you add may come with additional permissions . You should review what each dependency requires and what it's used for.

This also applies to end users: if a simple app requests a lot of permissions for no apparent reason, it might be using libraries that collect more data than necessary . In those cases, it's best to look for more user-friendly alternatives.

Be transparent with the information that is collected

Both Google and developers recommend that apps clearly explain what data they will use, why, and what happens if permission is not granted . As a user, you can look at these explanations (in the dialog box or on the Play Store page) to decide whether granting access is worthwhile.

If revoking a permission causes a function to stop working, it's a good idea for the app itself to show you an honest warning about why it's failing , instead of forcing you to accept it without explanation.

Indicators when using sensitive resources

When an app accesses the camera or microphone, Android already displays visual indicators (icons, lights, warnings, etc.). Even so, developers should add clear signals to their interface (for example, an active recording icon) to avoid any confusion for the user.

As a user, if you notice that an app is using these resources without you doing anything, it's the perfect time to go to settings and review or reset the permissions it has been granted.

How to reset permissions for all apps at once on Android

Let's get down to business: how can you clean up your phone by removing unnecessary permissions without having to check each app individually? Android offers several strategies for revoking permissions in bulk or almost automatically , especially in recent versions of the system.

Automatically remove permissions from apps you don't use

One of the most useful features is the option for Android to automatically revoke permissions for inactive apps . If you don't open an app for a while, the system removes certain sensitive access permissions so they don't remain active unnecessarily.

On many recent mobile phones you can activate this function by following a path similar to this (the names may vary depending on the brand):

• Open the app Settings of the telephone.
• Sign in Applications or "Applications and notifications".
• Select the specific application you want to configure (you can use "View all applications" if you don't see it at first).
• Tap on Permissions.
• Activate the option "Remove permissions if the application is not in use" (or an equivalent phrase).

Many systems already apply this globally to all installed apps, so after several months of inactivity, an app's runtime permissions are automatically revoked . When you reopen it, you'll need to grant the necessary permissions again.

Change app permissions on a per-app basis

If you want to do a more manual cleanup, you can always go into each app's settings to allow or deny exactly what it can do . The typical workflow on Android is:

• Opens Settings on your Android.
• Go to Apps / Apps and notifications.
• Choose the app you want to review.
• Sign in Permissions.
• You will see the Allowed and Denied permissions separated.
• Click on each permission to change it to Allow, Allow only when using the app, Always ask, or Deny (The specific options depend on the Android version).

In the case of highly sensitive permissions such as location, camera or microphone, Android usually offers more granular options, such as "Always allow" for location , although the latter is increasingly discouraged in favor of permission only when in use.

Reset permissions by type (permission manager)

If your priority is, for example, to review all the apps that can access your calendar or your SMS messages , the fastest way is not to go application by application, but to use the "Permission Manager" or "Permission Administrator" that Android includes.

The route is usually similar to this:

• Opens Settings on your mobile.
• Sign in Privacy policy or directly in "Permission Manager" (sometimes it's inside "Applications" > "Advanced").
• Select the type of permission you want to review (for example, Location, Camera, Microphone, SMS, Contacts...).
• You will see grouped the apps that are always allowed, only in use, or denied.
• Tap on each application to modify its setting for that specific permission.

This way you can, in a matter of minutes, reset the settings of a critical permission such as location for all your apps, leaving only the essential ones with access.

How to manage permissions with specialized applications

In addition to the options that come standard with Android, there are security tools and advanced permission managers that help you better control what each app does , especially if you have many installed or want to have a more detailed record.

Advanced permission managers

Some "App Permission Manager" style applications rely on Android's accessibility services to offer very complete panels with all the permissions of each app , categorized by risk level, and allow access to be revoked in bulk from a single interface.

Among the most common functions of these tools are:

• Overview of permissions by app and by riskThey distinguish between system apps, recent apps, and apps you want to keep forever.
• Analysis by permit typeYou select a specific permission and it shows you which apps use it.
• Control of special permitsThey identify which apps can modify system settings, ignore Do Not Disturb, draw over others, etc.
• Camera/microphone/location panel: a kind of dashboard where you can see which apps have recently used these resources.
• Permissions activity history: a detailed record of when each permit has been granted or used.

To offer these features, many of these apps ask you to enable the Accessibility Service , which allows them to simulate touches or navigate the interface to change permissions on your behalf. While this is very convenient, you should only use trusted apps, as this access is also sensitive and can be exploited by Android malware.

Mobile security solutions

Security tools, such as some antivirus suites for Android, also include modules for analyzing applications and their permissions . They usually warn you if an app requests too many permissions for what it appears to offer, or if it has a questionable history.

This type of software can help you detect fake applications, spyware, or malware that use permissions to do things they shouldn't, and in many cases makes it easier to uninstall or isolate them.

Permissions you should think very carefully before granting

Although you ultimately have the final say, there are certain permissions that should only be granted to extremely reliable apps , as they provide a fairly high level of control over the device.

Device administrator privileges

Administrator permissions allow an app to lock the phone, change passwords, or modify account settings . Some security or device management apps need them for functions like remote wiping in case of theft.

Even so, granting these privileges to an app of dubious origin is a very bad idea, because it could prevent you from uninstalling it or changing key system settings. Always check in Settings > Security > Administrator apps which apps have this type of access.

Root permissions

On rooted devices, certain apps can request superuser or root privileges , which grant them access to the operating system kernel. From there, they can do virtually anything: read, modify, or delete anything.

Some types of malware, such as rootkits , specifically seek these permissions to hide and control the device from within. If you're unsure what you're doing, it's best to never grant root permissions to any app.

When permissions fail or cause problems

Sometimes it's not that you've granted too much permission, but quite the opposite: an app might crash, freeze, or behave strangely because it lacks the necessary permission . This often happens after resetting permissions, when switching phones, or if the operating system has changed how it manages them.

If you notice that an app asks for the same permission repeatedly, or Android displays two dialogs in a row (one from the app and one from the system), clearing the Android cache or checking the settings of that specific application may help.

In some extreme cases (for example, apps installed outside the Play Store that require Accessibility in very recent versions of Android), Google and some manufacturers have added additional restrictions , making it even more difficult to grant certain permissions. In these situations, if you don't want to root your device, there may not be a perfect solution at the moment.

Ultimately, understanding these concepts and using the system's tools to your advantage gives you much more control over what each app can do with your data and your phone. Spending some time reviewing and resetting permissions can make the difference between a phone riddled with open doors and a reasonably secure and controlled device.
