Hi there! It sounds like you're having a bit of trouble logging into Local Now due to a frozen screen. Let's see if we can resolve this together!

1. Check Your Internet Connection: First, ensure your internet connection is stable. If you're on Wi-Fi, try toggling it off and back on again.

2. Restart the App: Close the Local Now app completely. You can do this by going to your recent apps and swiping Local Now away. After that, reopen the app and see if you're still stuck on the login screen.

3. Clear App Cache: If that doesn't work, we can try clearing the app cache:
- Go to your device’s Settings.
- Scroll down to Apps or Application Manager.
- Locate and tap on Local Now.
- Tap Storage and then select Clear Cache.

4. Try Logging In Again: After clearing the cache, relaunch the app and attempt to log in again.

5. Reboot Your Device: Sometimes, restarting your device can solve issues like this. After rebooting, try to log in once more.

6. Check for Updates: Make sure both your Android OS and the Local Now app are up to date. Go to the Google Play Store, search for Local Now, and see if there’s an update available.

If you still encounter the frozen screen, it might be beneficial to uninstall and then reinstall the app as a last resort.
