Hi there! I see that when you try to enter your NIF number in the LEROY MERLIN app on your Android 10 device, the screen goes completely blank, which prevents you from completing the process. Let's work through this together to get it sorted.

First, to better understand your situation:

- Are you using the latest version of the LEROY MERLIN app available from the Google Play Store?
- Have you tried restarting the app or your phone after the issue started?
- Does this happen only when entering the NIF number, or also in other parts of the app?
- Are you connected to a stable internet network while using the app?

Meanwhile, here’s a step-by-step guide to try fixing this:

1. Clear Cache and Data:
- Go to your phone's Settings > Apps > LEROY MERLIN app > Storage.
- Tap on “Clear Cache” first. If problem persists, tap “Clear Data” (note: this may log you out from the app).

2. Update the App:
- Open Google Play Store > Search for LEROY MERLIN > If an update is available, tap “Update”.

3. Reinstall the App:
- Uninstall the app completely, then reinstall it from Google Play Store.

4. Check Internet Connectivity:
- Ensure you have a stable internet connection, switch between Wi-Fi and mobile data to test.

5. Try a Different Device or Browser:
- If possible, try completing the NIF entry on another device or via the website to isolate whether the problem is app-specific.

If none of these solve the issue, there could be a bug related to your device’s WebKit browser engine or the Android 10 OS causing the app screen to go blank when accessing this specific input field.

Please let me know how these steps go or if you’ve already tried some of them. That way, I can suggest more tailored help! Are you satisfied with this plan so far?

Delete app and don't use.

I understand you want to delete the LEROY MERLIN app and stop using it. Here's how you can easily remove the app from your Android 10 device:

1. Go to your phone's Settings.
2. Tap on Apps or Apps & notifications.
3. Find and select LEROY MERLIN from the list of installed apps.
4. Tap Uninstall and confirm to remove the app completely.

Alternatively, you can also uninstall it directly from the home screen or app drawer by pressing and holding the app icon, then dragging it to the "Uninstall" option or tapping the uninstall button that appears.

If you want to ensure no account or data from the app remains linked, you might also want to log out of your account in the app before uninstalling, if possible.

Would you like me to guide you through deleting your LEROY MERLIN account as well, or is uninstalling the app sufficient for you? Are you satisfied with this solution?
