Fix Microsoft To Do Causes Android System UI Not Responding Error
Question details
Users are experiencing severe system freezing and error prompts on their Samsung smartphones due to compatibility issues with the Microsoft To Do application.

- Product
- Microsoft To Do
- Device & OS
- Android 13 (One UI 5.1)
- Scenario
- Using Microsoft To Do on Samsung Galaxy smartphones, particularly after receiving or dismissing app notifications.
- Observed behavior
- The Android device freezes completely and triggers a 'System UI is not responding' message, requiring users to wait or restart the device.
Ensure your Android device has enough battery life and is connected to a stable Wi-Fi network before updating system software or modifying app settings.
Disable Microsoft To Do Notifications
Since dismissing notifications triggers the system freeze, disabling the app's notification permissions provides a reliable temporary workaround.
User reports indicate that the 'System UI is not responding' error is directly tied to how One UI 5.1 handles Microsoft To Do's notifications. Turning them off entirely stabilizes the device, though you will have to check the app manually for task reminders.
Navigate to your Android device's Settings menu and select 'Apps'.
Scroll through your list of installed applications and tap on 'Microsoft To Do'.
Tap on 'Notifications' and toggle the switch to turn off 'Allow notifications'.

Update Device Software and Apps
Installing the latest software updates ensures you have the newest bug fixes from both Samsung and Microsoft.
Clear App Cache or Temporarily Uninstall
If tweaking permissions fails, clearing corrupted data or removing the app entirely will immediately restore normal device functionality.
Experience Stable Productivity with WPS Office
If you are tired of apps freezing your Android device or causing system UI errors, consider switching your document workflow to WPS Office. It is a highly optimized, lightweight alternative to Microsoft Office apps, ensuring smooth performance on all mobile devices without draining system resources.
- 1. Download the App: Visit the Google Play Store and search for WPS Office to download the application for free.
- 2. Open Your Files: Launch WPS Office and tap the '+' button or folder icon to open your existing Microsoft Office documents.
- 3. Work Without Interruptions: Enjoy editing your files on a stable platform that won't trigger Android System UI errors.

Frequently Asked Questions
Why does Microsoft To Do trigger the System UI error on Samsung phones?
The issue is caused by a compatibility bug between Microsoft To Do's push notification system and Samsung's One UI 5.1 (Android 13). Dismissing a notification from the app unexpectedly overloads or freezes the Android System UI process.
Will a factory reset fix the Microsoft To Do freezing issue?
No. According to extensive user testing, a factory reset does not resolve the issue. If you restore the phone and reinstall Microsoft To Do with notifications enabled, the freezing bug will return.
Is it safe to force stop the System UI process?
When the 'System UI is not responding' prompt appears, choosing to 'Wait' or 'Close app' is usually safer. Force stopping the System UI can temporarily blank your screen, though the device will typically reload the interface automatically within a few seconds.
