🛡� Post‑Install Setup & Best Practices

Enable two‑step verification in Telegram's Settings > Privacy & Security for enhanced account protection.

Review Privacy & Security settings: who can see your phone number, last seen, profile photo.

Be cautious when joining large public channels/groups—check moderation and source authenticity.

Regularly update the app to ensure you have latest security patches.

If you downloaded an APK outside the Play Store, make sure it's from the official site and the signature matches. Many "fake Telegram" apps exist.
