The first time you open any messaging app, it asks for access to your camera, microphone, contacts, and storage — and that’s expected, since none of the core features work without it: no sending photos, no voice messages, no synced contacts. The real question is different: how do you tell a normal, explainable set of permissions apart from one that’s already reaching beyond what a messenger actually needs?
The standard permission set for official Telegram
The official app’s permissions are fairly predictable and map cleanly onto its features:
- Camera and microphone — for photos, video, voice messages, and calls.
- Contacts — to find people you know who already use Telegram.
- Storage (files and media) — for sending and saving files, photos, and videos.
- Notifications — to show incoming messages.
This is the baseline that shouldn’t raise any questions in either the official app or an unofficial client — without it, the messenger simply can’t function as a messenger.
Extra permissions some mods ask for, and why
Unofficial clients sometimes request a wider set of permissions, and that’s not automatically a problem if the permission genuinely connects to a feature the app offers. For example:
- Location access makes sense if the client supports sending location pins or “nearby chats” features.
- Detailed contact information access may be needed for advanced sync features.
- Background activity is often needed for richer notification handling or automatic media downloads.
The rule of thumb is simple: a permission is worth granting when it’s clear why this specific client needs it for a feature it actually advertises.
Permissions worth paying closer attention to
A few permissions are harder to justify for a messaging app and deserve a closer look:
- Unrestricted SMS access. There are legitimate Telegram scenarios involving SMS (like receiving a login code on certain devices), but a standing, full SMS access beyond that is worth questioning.
- Access to the list of installed apps. A messenger doesn’t normally need this for its core functionality.
- Auto-start and unrestricted background activity. Moderate background activity is normal for push notifications, but a request to fully disable battery optimization is worth evaluating separately.
- Accessibility Service access. This is one of the most powerful permissions on Android — it lets an app read what’s on screen and simulate taps. A messenger very rarely needs this, and a request for it should come with a clear explanation of exactly which feature it enables.
How to check and revoke permissions on Android
You can review and change any installed app’s permissions in a few steps:
Settings → Apps → select your Telegram client → Permissions.
This shows the full list of requested permissions, and each one can be turned off individually — in most cases the app keeps working, with just the feature tied to that permission becoming unavailable.
The bottom line — a quick checklist
Before granting a permission, it’s worth asking one question: “does this permission connect to something I actually expect from a messenger?” A quick guide:
Normal: camera, microphone, contacts, storage, notifications, location (when used explicitly), limited background activity.
Worth questioning: full SMS access, access to the list of other installed apps, an Accessibility Service request with no clear explanation, a requirement to fully disable battery optimization.
This complements checking the APK for viruses — even a file that comes back clean from an antivirus scan is still worth evaluating based on what it asks for once it’s installed.
