Hi there! I see you're having trouble getting the NPS app to start on your Samsung Galaxy S23—it shows the NPS logo and then just hangs. Let’s work through this together and see if we can get it working for you.

A few quick questions to better understand the situation:
- Have you tried any troubleshooting steps already (like restarting the phone or reinstalling the app)?
- Is your phone’s software fully updated?
- Is the NPS app itself updated to the latest version from the Google Play Store?

Meanwhile, here’s a step-by-step approach we can try:

1. Force Stop and Clear Cache/Data of the NPS App
- Go to Settings > Apps > find NPS App.
- Tap Force Stop.
- Then tap Storage > Clear Cache. You could also try Clear Data if clearing cache doesn’t help (but this may log you out or reset app settings).

2. Check App Permissions
- Within Settings > Apps > NPS App > Permissions, ensure it has the necessary permissions enabled (like location, storage, etc.). Sometimes missing permissions cause apps not to launch properly.

3. Update Both the NPS App and Your Phone Software
- Open Google Play Store and check if the NPS app has an update. Install if available.
- Go to Settings > Software Update to check for any system updates for your S23.

4. Restart Your Phone
- After making the changes above, restart the device to refresh the system.

5. Try Running the App in Safe Mode
- Boot your phone into Safe Mode by holding the Power Off option and then selecting Safe Mode when it appears. This disables third-party apps temporarily and can help determine if another app is conflicting with NPS.
- Open the NPS app in Safe Mode. If it works here, then some other app may be causing conflicts.

6. Reinstall the NPS App
- If the app still hangs, uninstall it completely and reinstall from the Google Play Store. Sometimes app files get corrupted and a fresh install can fix that.

If after these steps the app still hangs at the logo screen, there might be a compatibility issue or bug with this specific phone model or OS version. From recent user reports, some apps have had trouble launching on the Galaxy S23, and steps like wiping the cache partition in recovery mode or checking for network mode settings have helped others2 3. If you're comfortable with that, I can guide you through those more advanced steps as well.

How about we start with the cache clearing and permissions check? Let me know how it goes or if you’ve already tried some of these!
