Note: Solutions in this guide will work on any Samsung Galaxy S20 model (S20, S20 Plus, S20 Fe, and S20 Ultra models.)

Editor’s note: We created these instructions using a Samsung Galaxy S20 running Android 13. Depending on your device’s software version, some steps and menu positions may look slightly different.

Many Samsung Galaxy S20 users who bought their phone from AT&T and other carriers have received a “Software update interrupted” error as shown in the below image when they tried to update their phone’s software.

Here is our explanation of why you get the “Software update interrupted” error on your Samsung Galaxy S20:

The error appears only on carrier-locked Samsung Galaxy S20 devices. This means the update was released to carrier-locked Galaxy S20 phones and for some reason it doesn’t get downloaded to these devices. It could be a server-side issue, where the update package is hosted, or could be a connection issue between the device and the server.

So is there a way to fix this? Yes. There are two ways you can fix this problem. These are:

1. Wait for another couple of days and check if the issue persists.
2. Check the internet connection, clear the system cache, reset network settings, and restart the device.

01 – Wait For Another Couple of Days

I write this article on 2024-03-05. But even a couple of months ago, the same problem had occurred and the reason for that error was a server issue. However, after a couple of days, Samsung did fix the problem and users were able to receive the update.

Samsung usually does not announce these types of issues via their official sites. Therefore, you need to wait for 1 – 2 weeks before checking for an update again, and I am pretty sure they will fix it if the problem is on their side.

But in the meantime, you can try the fixes below. These fixes are also proven to work and resolve the “Software Update Interrupted” error.
