Based on the screenshot, you are seeing a system error related to a background process called Desktop Mode Visual Indicator. This usually happens when a core system component (or a feature hidden in Developer Options) becomes unstable after an Android update.

​Since your screen isn't responding to touches, we need to bypass the UI to fix it. Here is how to resolve this:

​Step 1: Perform a Force Restart

​The most immediate way to regain control of your touch screen is a forced reboot.

​Press and hold the Volume Down and Power buttons simultaneously for about 7–10 seconds. ​The device should vibrate and restart. This often clears the temporary "freeze" caused by that pop-up. ​Step 2: Disable Desktop Mode (If accessible)

​The error mentions "Desktop Mode." This is often a hidden feature in Developer Options. Once your phone restarts and the screen works:

​Go to Settings > Developer Options. ​Search for Force desktop mode or Desktop Mode. ​Ensure it is toggled OFF. ​If you don't use Developer Options, you can simply toggle the main "Developer Options" switch to OFF at the very top of that menu. ​Step 3: Update System Apps

​Since you are on the latest One UI, some Samsung-specific background services might need an individual update through the Galaxy Store rather than the Play Store.

​Open the Galaxy Store. ​Tap Menu > Updates. ​Select Update all. ​Step 4: Clear System Cache (If the problem persists)

​If the pop-up keeps returning, there may be "junk" files left over from your recent Android update.

​Turn your phone off. ​Connect it to a PC or Mac via a USB cable (this is required for some One UI versions to enter Recovery). ​Press and hold Volume Up + Power until the Samsung logo appears. ​Use volume buttons to highlight Wipe Cache Partition and the Power button to select it. ​Once done, select Reboot system now.

​Note: This error is rarely caused by a virus; it is almost always a compatibility glitch between the Android OS and Samsung's "Desktop" (DeX) background services.

Thank you for reaching out. We understand that your Galaxy S series home screen is not responding to touches and you are receiving a persistent pop-up message.

This issue is usually caused by a temporary conflict in the "One UI Home" system service. Please follow these steps to resolve it:

1. Forced Restart: Since the screen is unresponsive, press and hold the Volume Down and Power buttons simultaneously for 7 to 10 seconds until the Samsung logo appears. This will force the system to refresh.
2. Clear One UI Home Cache: Once the device restarts, go to Settings > Apps. Tap the "Sort" icon (next to 'Your apps') and toggle on "Show system apps." Search for One UI Home, select Storage, and tap "Clear Cache."
3. Update System Apps: Open the Galaxy Store, go to Menu > Updates, and install any pending updates for "One UI Home" or "Samsung System" components to ensure compatibility with your current software.
4. Check in Safe Mode: If the pop-up returns, restart your device and hold the Volume Down button during the boot-up animation to enter Safe Mode. If the issue disappears in this mode, it confirms a recently installed third-party app is causing the conflict.

If the screen remains unresponsive after a forced restart, we recommend visiting an authorized Service Center for a hardware diagnostic: https://www.samsung.com/ae/support/service-center/
