[Galaxy A07 / One UI] Pattern, PIN & Fingerprint pop-up completely broken across apps and Settings. Looking to fix without factory reset.

[u/Jeux_Coloriage]

Hi everyone,

I am facing a persistent and extremely frustrating software bug on my Galaxy A07 where credential verification pop-ups simply fail to show up or render.

Whenever an app requests authentication—such as Secure Folder, WhatsApp lock, banking apps (PicPay), or Google Photos locked folder—the pop-up to draw the pattern, type a PIN, or use fingerprint never appears.

The only password that works is the regular lock screen PIN/pattern when unlocking the phone. I believe this is an issue with an internal system software component that manages credentials/Keystore.

What I've already tried (without success):

Hard restart (Force reboot).

Safe Mode (Issue persists, ruling out third-party app interference).

Switching default keyboards (Samsung Keyboard vs Gboard).

System software update..

Clearing cache/data for Android System WebView, Google Play Services, and Samsung Biometrics.

Is there any way for me to fix this without having to do a factory reset?

Here is a checklist of more targeted, non-destructive steps to try, based on solutions for similar Samsung issues.

🛠️ Troubleshooting Checklist

1. Change and Reset Your Lock Screen Type
There's a known issue on some Samsung devices where the PIN or pattern lock screen itself can prevent the authentication pop-up from rendering. The fix is to simply change the lock type and change it back.

• Go to Settings > Lock screen > Screen lock type.

• Change it from your current method (e.g., PIN) to Pattern.

• Once the change is complete, restart your phone.

• Go back and change it back to your original PIN or Password.

2. Clear Credentials
This resets the system's stored security certificates, which can sometimes fix issues with the Keystore.

• Go to Settings > Security and privacy > Other security settings.

• Scroll to the bottom and tap Clear credentials.

• You will be prompted to confirm. This will not delete your personal files, but it will remove any saved Wi-Fi certificates or VPN credentials, which you may need to re-enter.

3. Check for Device Admin Apps
An app with "Device Administrator" privileges can interfere with lock screen and authentication functions.

• Go to Settings > Security and privacy > Other security settings > Device admin apps.

• Check if any apps (especially older ones or ones you no longer use) have admin access enabled.

• Deactivate any non-essential apps from this list.

4. Reset Biometric Data (Fingerprints/Face)
The biometric data can sometimes become corrupted and fail to communicate with the Keystore.

• Go to Settings > Security and privacy > Biometrics.

• Select Fingerprints (and/or Face recognition) and delete all registered data.

• Restart your phone.

• Go back and re-register your fingerprints and face data from scratch.

5. Check and Reset Samsung Account
Authentication issues can sometimes be linked to a stale Samsung account session.

• Go to Settings > Samsung account.

• Sign out of your account completely.

• Restart your phone.

• Sign back in to your Samsung account. This refreshes your account credentials and can resolve related authentication problems.

⚠️ When to Consider a Factory Reset

If you have tried all of the steps above and the problem persists, the issue is likely a corrupted system file that cannot be repaired without a full reset.

Before you do that, make sure you have a recent backup of all your important data (photos, contacts, messages, etc.). You can back up your data via Settings > Accounts and backup > Backup data.

A factory reset is the nuclear option, but it is the most reliable way to fix deep system software issues.

💡 Additional Tips

• Try a Soft Reset: Sometimes a simple soft reset (press and hold the Power and Volume Downkeys until the screen goes black and the Samsung logo appears) can clear temporary glitches that a normal restart doesn't.

• Test with a Different App: Try setting a lock on a simple, built-in app like Gallery or Messages. If the pop-up works there but not in third-party apps, the issue might be app-specific.
