Last updated: September 2025
Problem
Telegram crashes, freezes, or closes unexpectedly when you open it, send messages, or use calls/media. This usually happens due to outdated apps, corrupted cache, low storage, or OS conflicts.
Solution
Fix Telegram crashes by updating the app, clearing cache, ensuring enough storage, and reinstalling if necessary.
Step-by-step Instructions
Step 1: Update Telegram
- Open the Google Play Store (Android) or App Store (iOS).
- Search for Telegram.
- Tap Update if available.
Step 2: Restart your device
- Reboot to clear temporary memory and system glitches.
Step 3: Clear Telegram cache
- Android:
- Go to Settings > Apps > Telegram > Storage & Cache.
- Tap Clear Cache.
- iPhone:
- Open Telegram > Settings > Data and Storage > Storage Usage.
- Tap Clear Cache.
Step 4: Free up storage space
- Ensure at least 1–2 GB free space on your device.
- Delete unused apps, large videos, or offload files to cloud storage.
Step 5: Reinstall Telegram
- Backup important media (Telegram will re-sync chats from the cloud).
- Uninstall Telegram.
- Reinstall from Play Store/App Store.
- Log in with your phone number.
Step 6: Update your operating system
- Android: Settings > System > Software Update.
- iPhone: Settings > General > Software Update.
Optional Methods or Tools
- On Android, check if third-party apps (e.g., cleaners, task killers) interfere — disable or uninstall them.
- On jailbroken/rooted devices, restore to official OS to avoid instability.
Best Practices / Tips
- Regularly clear Telegram cache to prevent data corruption.
- Keep both the app and your OS updated for stability.
- Ensure automatic cloud sync so you don’t lose chats if you need to reinstall.
- Avoid using unofficial Telegram clients or mods — they often cause crashes and are less secure.
