Hello! It sounds like you're experiencing an issue where the LifeLock Identity app launches but then immediately closes on your Android device. Let's work together to find a solution for this.

First, may I ask if you've already tried any troubleshooting steps to resolve the issue? If not, we can start with some simple steps to see if we can get the app working:

1. Restart Your Device: Sometimes, a simple restart can resolve temporary glitches. Just turn your device off, wait a few seconds, and then turn it back on.

2. Clear Cache and Data for the LifeLock App:
- Go to Settings on your device.
- Tap on Apps or Application Manager.
- Find and select LifeLock Identity.
- Tap on Storage and then select Clear Cache. If the problem persists, you may also try Clear Data (note that this will reset the app, and you might need to log in again).

3. Check for Updates: Ensure that both your Android operating system and the LifeLock app are up to date.
- For the LifeLock app, go to the Google Play Store, search for "LifeLock", and see if an update is available.
- To check for system updates, go to Settings > System > Software update.

4. Reinstall the App: If the above steps didn't resolve the issue, uninstall the LifeLock app and then reinstall it from the Google Play Store.

If you've already tried these steps or if the issue persists, please let me know, and we can look into more advanced troubleshooting options. How does that sound for a start?
