When the System UI stops working on your Android device, you may experience problems such as the screen freezing, Apps closing, buttons not responding, problems with notifications, or even the device rebooting.

But do not worry. There are several methods you can use to fix this problem. These methods range from simple solutions like restarting your device to more complex ones like resetting your device to factory settings. In this guide, you will learn all these simple methods, and you will be able to fix the problem easily.

How To Fix the System UI Is Not Responding

Restart Your Smartphone

Let’s start with the simplest and most efficient troubleshooting method: restart your Smartphone. When you restart your phone, all running apps and services will be closed, including the System UI. When you turn your phone back on, your device will reboot.

In addition, restarting your smartphone has other benefits, such as speeding up your phone by closing apps that slow it down, saving battery life by disabling apps you don’t need, deleting files you don’t need to free up storage space, and cooling your phone when it gets too hot. You can restart your smartphone simply by long pressing the power button and selecting the “Restart” option.

Clear System UI Cache

Another easy way to fix this is to clear the System UI cache. The System UI cache is a place where your phone stores temporary data that helps System UI to work properly.

To fix this, you can simply clear the cache of the System UI app on your Android smartphone.
