Hi there! Thanks for reaching out. I understand you're seeing a black screen when you log on to the Scavenger Hunt game on your Windows 10 device, and you've already tried reinstalling the app and clearing the cache. Let's work through some other possibilities to get you back into the game.

First, just to clarify:
- Are you running the game directly in a browser with WebKit, or is this a desktop app?
- Also, when you say you cleared the cache, was that clearing the browser cache or an in-app cache?
- Are there any error messages or does it just stay black?

In the meantime, here’s a step-by-step approach based on what usually helps with black screen issues on Windows with games:

1. Check Internet Connection: Make sure your internet is stable and fast enough, as the game might get stuck loading resources. Try switching between Wi-Fi and wired if possible.

2. Update Graphics Drivers: Outdated display drivers can cause rendering issues. On Windows 10, you can update your graphics driver by:
- Press Windows + X, select Device Manager.
- Expand Display adapters, right-click your graphics card, and choose Update driver.
- Select “Search automatically” and install any found updates.

3. Disable Hardware Acceleration (Browser-specific): Since WebKit is your rendering engine, if you’re playing via a browser like Safari or a WebKit browser, disabling hardware acceleration can help:
- For instance, in Chrome (Chromium-based), go to Settings > Advanced > System and toggle off “Use hardware acceleration when available.” Then restart the browser.

4. Run the Game as Administrator: Right-click the game executable or your browser and choose “Run as administrator.” Sometimes this fixes permission-related rendering issues.

5. Check for Background Apps: Some apps may interfere with games. Try closing down background apps, especially screen-recorders or firewall/antivirus programs temporarily to see if they might be causing a block.

6. Clear Local Storage and Cookies for the Game Site (If Browser-based): Sometimes browser cache clearing doesn’t remove site-specific data. In your browser settings, look for site data related to the game domain and clear that.

7. Try a Different Browser: If possible, try launching the game in a different browser (like Chrome, Edge, or Firefox) to see if the black screen persists.

If you've tried these or if anything sounds new or different with your setup, please let me know! We can then dive deeper into more advanced settings or check if there might be server-side issues affecting access.

Are you comfortable trying these steps, or would you like me to guide you through any of them more specifically?

The app black screen is on an Android phone. Have uninstalled and reinstalled the app, cleared the cache and still a black screen

Thanks for the update! Since the black screen is happening on your Android phone despite reinstalling and clearing the cache, let's try some additional steps that others have found useful with similar app issues:

1. Restart Your Phone: Sometimes a fresh reboot can clear temporary glitches. Press and hold your phone’s power button and select Restart or Power off and then turn it back on3.

2. Clear App Data (Not Just Cache): Clearing cache removes temporary files, but app data clearing resets the app completely. Here’s how:
- Go to your phone’s Settings > Apps or Application Manager.
- Find the Scavenger Hunt app.
- Tap Storage, then choose Clear Data. This may log you out, but can fix persistent issues1.

3. Check Permissions: Make sure the app has all necessary permissions granted (Storage, Network, etc.). You can check this under Settings > Apps > Scavenger Hunt > Permissions.

4. Update Your Android OS: Sometimes older system versions cause compatibility issues. Go to Settings > System > Software Update and install any available updates.

5. Try Clearing Background Apps: Close other apps running in the background to free memory—this can sometimes resolve display issues.

6. Uninstall and Install from Official Store: Double-check you have the latest version from the Google Play Store.

If these don’t resolve the black screen, it might be related to a recent bug or compatibility problem with your specific phone model or OS version. If you can share your phone brand/model and Android version, I can look into device-specific guidance.

Would you like me to walk you through clearing app data or checking permissions? How is your phone’s performance generally?

Phone is a Samsung galaxy 25 ultra

Thanks for sharing your phone model—Samsung Galaxy S25 Ultra is a powerful device, and that's helpful to know!

Regarding the compatibility of the Scavenger Hunt app with your phone, Scavenger Hunt supports all mobile devices, including Android phones like the Samsung Galaxy series, through official downloads from Google Play1. While specific mention of the S25 Ultra isn't listed, the app should work smoothly on this latest model.

Since the device should be compatible, and you've already reinstalled and cleared cache, let's try these phone-specific steps next:

1. Clear App Data: Please clear the app data fully (Settings > Apps > Scavenger Hunt > Storage > Clear Data), as that resets the app beyond just cache.

2. Check Permissions: Confirm that all permissions (camera, storage, location, etc.) are granted, as missing permissions could cause rendering issues.

3. Update Phone Software: Ensure your S25 Ultra is running the latest Android version and security patches by checking Settings > Software update.

4. Check Game Version: Verify the app is the latest version from the Google Play Store.

5. Try Safe Mode: Boot your phone into Safe Mode to see if any third-party apps may be interfering. In Safe Mode, only essential system apps run. To enter Safe Mode on Samsung devices:
- Press and hold the power button.
- When the power off icon appears, press and hold it until 'Safe mode' appears.
- Tap 'Safe mode' to reboot.
If the game works in Safe Mode, another app may be conflicting.

6. Contact Support: If none of these steps resolves the black screen, please email [email protected] with your phone details and a description of the problem for further investigation.
