Thank you for the information! Since you're unable to open PDF, Excel, and Word documents without any error messages, let's try a few steps to troubleshoot this issue. It might be a problem with the apps you're using or their settings. Here’s a simple guide to help you out:

### Step 1: Restart Your Device
1. Power off your Android device completely.
2. Wait a few moments, then turn it back on.
3. Try opening the documents again.

### Step 2: Check Your App Permissions
1. Go to Settings on your device.
2. Tap on Apps or Applications.
3. Find and select the app you’re trying to use (like Adobe Reader for PDFs, Excel, and Word).
4. Check the Permissions section and ensure that all necessary permissions are granted.

### Step 3: Clear App Cache
1. Head back to the Settings and go to Apps.
2. Select the app you want to clear the cache for (e.g., PDF, Word, or Excel).
3. Tap on Storage.
4. Choose Clear Cache.
5. Now, try to open your documents again.

### Step 4: Update Your Apps
Even if there are no system updates, make sure your document apps are up to date.
1. Open the Google Play Store.
2. Search for your apps (PDF reader, Word, Excel).
3. If there's an Update button, tap it.

### Step 5: Reinstall the Apps
If the problem persists, consider reinstalling the applications:
1. Go to Settings > Apps.
2. Select the app (PDF reader, Word, or Excel) and choose Uninstall.
3. After uninstalling, go to the Google Play Store, and reinstall the app.

If none of these steps work, it might indicate a deeper issue, and we can explore other options. Just let me know how it goes so far! Are you satisfied with these steps, or do you need more help?
