How to Review and Manage App Permissions on iPhone and Android

Published 2026-10-16 · Marion Phone Repair

Every app on your phone has a set of permissions — access to your camera, microphone, location, contacts, photos, and other data. You granted most of these permissions during initial setup or the first time you used a feature, often tapping Allow without thinking about it. Over time, apps accumulate permissions they no longer need or never should have had. This guide walks through auditing your app permissions to ensure apps only access what they actually need.

Why app permissions matter

Privacy: An app with camera permission can potentially access your camera. An app with microphone permission can listen. An app with location permission knows where you are. Most apps use permissions legitimately, but excessive permissions create risk — especially if the app is later compromised or sold to a new company with different practices
Battery life: Apps with background location access, constant microphone access, or frequent sensor access drain battery. Restricting unnecessary permissions directly improves battery life
Data exposure: Apps with contacts permission can read your entire address book. Apps with photo access can read all your photos and their metadata (including location data embedded in photos). The less data an app can access, the less it can collect or leak

Audit permissions on iPhone

Review by permission type

This is the most effective approach — see every app that has a specific permission at once:

Open Settings, Privacy and Security
Each category is listed: Location Services, Contacts, Calendars, Reminders, Photos, Bluetooth, Local Network, Microphone, Speech Recognition, Camera, Health, HomeKit, Media and Apple Music, Files and Folders, Motion and Fitness, Focus
Tap each category to see which apps have access. Review each one and ask: does this app need this permission to function for what I use it for

Location permissions (most important)

Location is the most sensitive permission and the most commonly over-granted:

Settings, Privacy and Security, Location Services shows every app with location access
Each app has one of four settings: Never, Ask Next Time or When I Share, While Using the App, or Always
Always means the app can access your location even when you are not using it. Very few apps legitimately need this. Navigation apps, fitness trackers, and weather apps with severe weather alerts are reasonable. Social media, shopping, and news apps do not need Always access
While Using the App is appropriate for most apps that use location — maps, ride-sharing, local search, weather. The app gets your location only when open and visible on screen
Never for apps that do not need your location at all. Games, note apps, calculators, and most utility apps have no legitimate reason to know where you are
Also check Precise Location vs Approximate Location for each app. Approximate Location gives apps your general area (city or neighborhood) without pinpointing your exact address. Social media and weather apps work fine with approximate location

Photo access

Settings, Privacy and Security, Photos shows apps with photo access
Options are None, Limited Access (you choose specific photos the app can see), or Full Access (the app can see all your photos)
Limited Access is the best default for most apps. When an app asks for photos, grant Limited Access and select only the photos you want to share. The app cannot see the rest of your library
Only apps that legitimately manage or edit your photo library (dedicated photo editors, backup apps) need Full Access

Camera and microphone

Review which apps have camera and microphone permissions. Green and orange indicator dots appear in the status bar when an app is actively using the camera or microphone
Revoke camera access from apps that do not need it. A shopping app does not need your camera unless it has a barcode scanner you actually use
Revoke microphone access from apps that do not need voice input. Many apps request microphone permission during setup even if you never use voice features

Audit permissions on Android

Permission manager

Open Settings, Privacy (or Security and Privacy on Samsung), Permission Manager
This shows permissions grouped by type: Body Sensors, Calendar, Call Logs, Camera, Contacts, Files and Media, Location, Microphone, Nearby Devices, Notifications, Phone, Physical Activity, SMS
Tap each permission type to see which apps have access, organized into Allowed, Allowed Only While in Use, and Denied

Location permissions on Android

Settings, Privacy, Permission Manager, Location
Apps are categorized as Allowed All the Time, Allowed Only While in Use, Ask Every Time, or Denied
Apply the same logic as iPhone: very few apps need location all the time. Downgrade most apps to While in Use or Denied
Check Use Precise Location for each app. Toggle off precise location for apps that only need approximate location

Unused app permissions (Android 11 and later)

Android automatically revokes permissions from apps you have not used in a few months:

Settings, Apps, select an app, Permissions shows current permissions and whether auto-revoke is enabled
Pause App Activity If Unused (or Remove Permissions If App Is Unused) automatically removes permissions from apps you do not open. This is a useful safety net but does not replace a manual review

Privacy Dashboard (Android 12 and later)

Settings, Privacy, Privacy Dashboard shows a timeline of which apps accessed your location, camera, and microphone over the last 24 hours
This is the quickest way to spot unexpected permission use. If an app accessed your microphone at 3 AM and you were not using it, that is worth investigating

Common permission over-grants

Flashlight apps: A flashlight needs access to the camera flash. It does not need location, contacts, phone, or microphone. Many free flashlight apps request excessive permissions to collect data. Modern phones have a built-in flashlight toggle — delete third-party flashlight apps entirely
QR code scanners: Your phone camera app (both iPhone and Android) scans QR codes natively. Third-party QR scanner apps often request unnecessary permissions. Delete them and use the built-in camera
Weather apps: Approximate location is sufficient. Weather does not change meaningfully between your exact address and your general neighborhood. Deny precise location and deny Always access — While Using or even manual city selection works fine
Social media: Review whether each social media app needs camera, microphone, contacts, and location access. If you never post photos or video through the app, it does not need camera or microphone. If you never share location or use nearby features, deny location access
Shopping apps: Rarely need anything beyond notifications. Camera permission is reasonable if the app has a barcode scanner. Location, contacts, and microphone are not needed for shopping

Permissions to check periodically

Set a reminder to review permissions every 3 to 6 months:

New permissions get granted over time as you install apps and quickly tap Allow
Apps update and may request new permissions you did not originally grant
Your usage patterns change — an app you used daily last year might be unused now but still has full permissions
