Android 12 System UI Not Responding? How to Fix in 12 Ways

Google’s latest OS for Android mobiles, Android 12 rolled out to the general public in the first week of October 2021. Third-party manufacturers are also gradually rolling out Android 12 with their own garnishing up top. By the end of the year, almost all flagships from leading manufacturers will have Android 12, which is exciting, to say the least.

Today, however, is not about addressing the exciting features Android 12 has brought, it is about the system crashes users early adopters are facing. Now without further ado, let us get to it.

What are the possible causes of Android 12 System UI not responding?

After months of beta testing, Android 12 was released in October 2021 to much fanfare. However, even with strenuous beta testing, bugs have remained and it is likely to stay that way for a few months. When your System UI stops responding, it is generally due to under-optimization or shortage of RAM. So, make sure your device has at least 6GB of RAM before you have a go at Android 12. 

You should also refrain from installing applications from unknown sources. They could potentially carry malware and make your system unstable. Additionally, make sure you have sufficient internal memory available before installing big updates. Those can also mess up the sanctity of your system.

How to fix Android 12 System UI not responding issue in 12 ways

Android 12 has a few optimization issues, but most of them could be brushed aside if you are determined enough. Below are the top 12 fixes for freezing issues of the System UI. 

Solution #1: Close heavy applications

Lack of primary memory or RAM is one of the biggest contributors to system instability and freezes. So, always make sure Android 12 has enough RAM to play around with. Killing heavy apps is the fastest way to achieve this. Pull up from the bottom of your screen and hold to access the Recent Apps screen. Kill the apps that you are not currently using by swiping up an app’s window.

Some apps or graphic-intensive games end up running in the background even after you swipe them away from your Recent apps screen. To make sure they’re closed, tap on their app icon in Recent apps, select ‘App info’, and then tap on the ‘Force stop’ option.

Solution #2: Boot in Safe Mode

System UI freezes also occur due to unoptimized third-party applications. So, if you suspect third-party apps are at fault, you should try to boot your phone into Safe Mode. Safe Mode only runs the essential system apps and services, which would negate any adverse effects the third-party apps might be having on the system.

To boot your Android 12 device into Safe Mode, first, press and hold the power button. When the Power Menu appears, long-press the Power Off button, until you see the ‘Reboot to safe mode’ prompt. Here, tap on ‘Ok’ to successfully restart the phone into safe mode.

Solution #3: Uninstall Google Updates

Google Updates are generally meant to stabilize your phone, improve security, and even add features. However, every once in a while it loads half-baked updates, which make your device act a little erratic. So, if booting in Safe Mode and killing applications do not do the trick, we would recommend uninstalling Google updates as well. 

To uninstall the updates, first, go to Settings, tap on ‘Google.’ It could be hidden under the ‘Apps’ section as well. Alternatively, you can get to this screen by long-pressing the Google app icon and selecting the ‘App info’ option. Now, tap on the vertical ellipsis button and then hit ‘Uninstall Updates.’

It will prompt Google to uninstall newly-install updates right away.

Solution #4: Clear cache of System UI

If you are running a non-vanilla Android 12, such as Samsung’s One UI, clearing the System UI might come in handy. To clear the System UI, first, go to Settings and tap on ‘Apps.’ If you are on Samsung’s One UI, you will find the One UI Home option in there. Tap on it to open. Finally, hit ‘Clear Cache’ to do a proper cleanse.

With that out of the way, you should restart your device to see if it fixes the erratic system crashes. 

On a Google Pixel device, you will have to clear the Google Pixel Launcher cache to apply the solution. 

Solution #5: Reset app preferences

Android is all about customizability, so it makes perfect sense for the OS to allow you to reconfigure your default applications. Unfortunately, that often comes with unanticipated side effects. To get rid of the said side effects, we recommend you reset the app preferences from settings. For this, go to Settings > System > Reset options. On the next screen, tap on ‘Reset app preferences’ to reset the app preferences to factory settings.

Solution #6: Clear cache in recovery mode

Before going ahead, we would like to tell you that very few devices allow you to clear your system cache. OnePlus is probably the biggest champion of deep-level customization, as they are the only major player to offer the option of clearing cache. 

To get into recovery mode, you will need to press and hold the volume down button and power button together. Hold them until you see the Android mascot icon. Now use the Volume keys to navigate and Clear the System Cache. 

Solution #7: Update Google Play Services

Not updating your Google Play Services can also lead to system-wide slowdowns. Usually, these services are updated automatically in the background. However, that process is not foolproof and can be interrupted by other processes. So, make sure to update them for a hassle-free transition to Android 12.

To update Google Play Services, go to Settings > Apps, and then, locate the Google Play Services app. Inside the App info screen, scroll down and tap ‘App details’. This will launch the Play Store app with the Play Services app listing open. Here, tap on ‘Update’ if available.

Solution #8: Remove widgets from the home screen

Android 12 is still in its early days, meaning not many apps and widgets have been able to adhere to the new OS’ regulations. In doing so, they are not only failing to make the most of the new system, but they are also running the risk of making their consumers’ phones sluggish. 

Widgets, in particular, can make your life particularly difficult, as they actively interfere with your Home screen browsing. So, if you happen to have widgets on your home screen, we would recommend removing them at once. Press and hold anywhere on the home screen to get to options. Now, long-press on the widget you want to remove and drag it to the ‘Remove’ option at the top of the screen.

Solution #9: Turn off GIF playback in Discord

If the System UI is crashing while using Discord, you should disable automatic playback of GIF files. To disable it, first, tap on your profile picture at the bottom of your screen. Now, go to ‘App Settings.’ Next, tap on ‘Text & Images.’ Finally, disable the toggle on the right of ‘Automatically play GIFs when possible’.

Solution #10: Look for software update

A software update is the best way to get the most stable version of Android 12. Developers tend to push software updates pretty regularly early in the lifecycle, which is programmed to solve the most blatant issues. To update your phone to new software, go to Settings > System > System update, and then tap on ‘Check for update’ to check for the updates manually.

When an update is available, it will appear on the screen, and from there, you can update it accordingly.

Solution #11: Perform a factory reset

Performing a factory reset will delete everything from your phone, but is another reliable way of fixing issues with consistency. You will need to go to Settings > System > Reset > Erase all data (factory reset) to reset your phone.

If you cannot find it, just tap on the search bar at the top of your screen and look for “Factory reset.” It should guide you to the option. Set the device up as new and you will be set. 

Solution #12: Look for hardware failures

Dropping your phone or exposing it to dust or water can lead to critical hardware failures. These issues can make the system unstable and the System UI unresponsive. If you suspect anything of that sort, we would recommend you to take it to your nearest service center for a thorough examination.
