Android App Permissions Explained: A Complete 2026 Guide

Android's permission system is the single most important privacy control on your phone, and it has quietly become very powerful. On Android 12 and later, every sensitive resource — camera, microphone, location, body sensors, files, contacts, calendar, SMS, call logs, nearby Bluetooth devices — is gated behind an explicit prompt and can be revoked at any time. The catch is that most people grant permissions in the moment without thinking, then never look at them again.

How Android permissions work

Permissions fall into three tiers. Normal permissions (internet access, vibration) are granted automatically because they pose minimal risk. Runtime permissions are the ones Android prompts you about — these are the dangerous-by-default category. Special permissions like "Display over other apps" or "All files access" require you to dig into Settings to grant them and should be treated with even more suspicion.

Runtime vs install-time permissions

Before Android 6, apps declared every permission they needed at install and you took it or left it. Today, apps must ask in context, and you can choose "Only this time", "While using the app", or "Don't allow". The "Only this time" option is genuinely temporary — Android revokes it as soon as the app closes — and it's the right answer most of the time you're not sure.

Auditing every app on your phone

Open Settings, then Security & privacy, then Privacy, then Permission manager. You'll see one entry per permission type. Tap Location, for example, and Android shows you every app that has access, grouped by "Allowed all the time", "Allowed only while in use", "Ask every time", and "Not allowed". Work through Camera, Microphone, Location, Files and media, and Contacts in that order. Anything you don't remember installing or don't use weekly should be dropped to "Don't allow".

Revoking access safely

Revoking a permission never uninstalls an app, and modern apps are required to handle a denied permission gracefully — they should either skip the feature or prompt you again the next time you try to use it. The one exception is apps that haven't been updated in years; Android will auto-revoke permissions for unused apps after a few months, which is usually what you want.

Five settings to change today

1. Turn off background location for every app except maps and ride-sharing. 2. Set the microphone to "Ask every time" for any app that isn't a calling or recording app. 3. Switch your default browser's location permission to "Don't allow". 4. Remove "All files access" from any app that doesn't truly need it. 5. Visit Privacy dashboard (Settings > Security & privacy > Privacy > Privacy dashboard) once a week for a month — you'll be surprised what's running in the background.
