Why does my Galaxy S21 Ultra crash after Android 13 update?

Official thread in samsung community

If you’ve been using Samsung Galaxy smartphones for a while, you’re probably aware that this isn’t the first time they’ve crashed after a software update.

The most obvious reason is that the update contains a few bugs and glitches. But this is not the reason every time. Some apps and services are still not updated to support the Android 13 update. Therefore, those apps and services can become unresponsive when you use them.

Another reason that your Galaxy S21 crashes is that there are a few things that you should do after an update. These include clearing cache, resetting network settings, running app repairs, etc. If these aren’t done, then it can cause your smartphone to crash randomly.

Now let’s see what you need to do to fix this problem.

Solutions to fix Galaxy S21 Ultra crashing problem

Some of these solutions have been tested by Galaxy S21 Ultra users, and we have included the other possible solutions as well. Also, these methods can be tried on other S21 versions (S21, S21+, and S21FE) as well.

Fix 01: Clear the system cache 

As I said earlier, when you update the software, it is always better to clear your smartphone’s cache. It is because the cached data helps your smartphone work efficiently.

However, using old cached data on the new Android version can cause the apps and the system to crash.

Follow the steps below carefully to clear the cached data on your Galaxy S21 by using the recovery menu.

  1. Power off your smartphone
  2. Press and hold the Volume up + Power button and wait for your device to boot into recovery mode.
  3. Release the keys when you see the recovery menu. And navigate to “Wipe cache partition” using the volume buttons.

  1. Press the power button. You will get a prompt to confirm and press the power button while selecting the “Yes” option to confirm.
Confirm wipe cache
  1. Wait until all the cached data gets cleared. You will see the recovery menu again and navigate to “Reboot system now” and press the power button to restart the device.

Now you can check if this solution works.

Fix 02: Reset All Settings

This solution is very similar to clearing cached data. But what we are going to do here is reset all previously applied settings to default values.

The reason to do this is the same. We are removing previously applied settings, which will restore the values to their original state. Then you can change the settings as you want.

  1. Navigate to Settings > General Management.
  2. Tap on “Reset” option.

  1. From the list, Tap “Reset all settings”.
Reset all settings
  1. Confirm.
  2. Once it is done, Restart the device.

Fix 03: Update Apps

It has been three months since the Android 13 update rolled out. Many developers have already updated their apps to support the latest Android version.

Therefore, you can update the apps to the latest version to get support for Android 13, and by updating apps, you can prevent the apps from crashing on your Galaxy S21 device.

  1. Open Google Play Store.
  2. Tap the profile icon at the top right corner.
  3. Tap on “Manage apps and device”.
Manage apps and devices
  1. Tap the “Manage” tab.
  2. From the top buttons, tap “Updates available”.
Updates available
  1. You will see the list of app updates that are available. Select all apps and tap on “Update”.
  2. After updating all apps, restart the device.

Fix 04: Repair Apps

If updating apps did not work and your S21 keeps crashing, you could try to repair apps in “recovery mode.” This option will repair the file system if it is damaged or corrupted during the software update.

Here is how you can repair all the apps on your Samsung Galaxy S21.

  1. Boot your device into recovery mode (As you did in the Fix: 01)
  2. Once your smartphone boot into recovery mode, navigate to “Repair apps” and press the power button.

  1. If you get a message to confirm, select “Yes” and press the power button.
  2. After the process is finished, navigate to “Reboot system now” and press the power button again to restart your phone.

Fix 05: Factory data reset

If nothing worked for your Galaxy smartphone, then the last step is to reset your S21 to factory settings. But the main problem here is that by doing this, all of your personal data will be removed from your phone.

Therefore, if you are willing to do a factory reset, then take a backup of all your personal files on a cloud drive or to an external storage device first. Then charge your phone up to 80% of its capacity.

Then you can safely proceed to do a factory reset on your smartphone. Here is what you need to do.

  1. Open Settings > General management.
  2. Tap Reset > Factory data reset.
Factory data reset
  1. You will be asked to enter the screen lock password (If you have set a screen lock). Type it and press the “Ok” button.

Now your device will boot into recovery mode and the factory data reset will begin. It will take a while to complete the process so be patient.

Your Galaxy S21 will restart after the factory data reset is done and you can check if the crashing problem is gone.


If your Galaxy S21 Ultra (or any other version) is still crashing after correctly following all the above steps, then you can send a report to Samsung by using the Samsung Members app. You can also contact a support agent through the app, and an expert will take care of the problem afterward.
