The firmware build number for the carrier-locked Galaxy S23 phones in the US is S91*USQU1BWK4. The OTA (over-the-air) download size is close to 3.3GB for the Plus model. Other models should be getting a similar-sized update package. Beta users may get a smaller package. However, make sure you download the update on Wi-Fi, or you’ll be wondering where all your cellular data went.
The update is currently live on T-Mobile‘s network, but it should be available on other networks soon, including unlocked units. You’ll get a notification when the update is available for your phone, but you can also manually check for new OTA releases in the Settings app.
Here’s how to check for the update:
- Open the Settings app.
- Navigate to Software update.
- Tap Download and install.
If you have a Galaxy S23 series phone in the US, be sure to check for the One UI 6.0 update. One UI 6.0 is a big update based on Android 14. It includes dozens of new features and design changes, including a revamped notification panel and Quick Settings, with a cleaner and more organized look. With the update, you can also enjoy improved system animations, widgets, and enhancements to stock apps, such as the camera and gallery.
