2. Select "Apps" or "Application Manager."
3. Find and tap on "Signal" from the list of installed apps.
4. Tap on "Storage."

2. Update Signal
Keeping your apps up to date is essential for smooth performance. Signal regularly releases updates that fix bugs and improve stability. Updating the app might address the crashes you are experiencing.
To update Signal on your Android device:
1. Open the Google Play Store.
2. Search for "Signal" in the search bar.
3. If an update is available, you will see an "Update" button. Tap on it to update Signal to the latest version.

Restarting your Android device is a simple but effective solution for resolving various app-related issues. It clears temporary files and resets processes, which can help fix Signal crashes.
To restart your Android device:
1. Press and hold the power button on your device.
2. Tap on the "Restart" or "Power off" option.
3. Wait for your device to restart completely.
4. Launch Signal and check if the crashes persist.
