Hi there! I understand you're having trouble logging into the My Memorial Hermann app on your Android phone after setting up your PIN or password. Let's work through this together.

To better assist you, could you tell me:
- Are you seeing any error messages when you try to log in?
- Did you recently change your PIN or password, and are you sure you're entering the correct one?
- Have you tried logging in with your username and password instead of the PIN?
- Is the app up to date from the Google Play Store?

Meanwhile, here are some straightforward steps to try first:

1. Restart the app: Close the app completely and reopen it.
2. Verify your login credentials: Make sure you are entering the correct PIN or password—sometimes it helps to toggle the "show password" option if available.
3. Use your full username and password: If the PIN login isn’t working, try logging in with your full account credentials.
4. Clear app cache: On your Android phone, go to Settings > Apps > My Memorial Hermann > Storage > Clear cache. Then try logging in again.
5. Update the app: Make sure the app is updated to the latest version on Google Play.

If none of those help, we could try resetting your PIN or password through the account recovery options in the app or on the My Memorial Hermann website.

Let me know what you’ve tried so far or if you see any specific errors, and we can go deeper from there!
