Samsung has started rolling out the August 2023 security update for its flagship Galaxy S23 series, making it one of the first devices to receive the latest Android security patch. The update not only fixes several vulnerabilities in the Android OS and Samsung’s software, but also brings some camera enhancements and stability improvements.
What’s new in the August 2023 security update for Galaxy S23?
The August 2023 security update for the Galaxy S23 series is a hefty one, weighing around 1.4 GB in size. The update is currently live in Thailand and Malaysia, but it should soon expand to other regions as well. The firmware version is S91xBXXU3AWGJ for all three models: Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra.
According to Samsung’s release notes, the update improves the performance and stability of the device, as well as the camera quality. However, the company does not specify what exactly has changed in the camera department. Some users have reported that the update improves the autofocus speed and accuracy of the Galaxy S23 Ultra’s 108 MP main camera, which was previously criticized for being inconsistent and slow.

The update also includes the August 2023 Android security patch level, which addresses multiple vulnerabilities in the Android runtime, framework, system, and media framework. Additionally, the patch fixes some issues in closed-source vendor components and the Linux kernel. You can read more about the details of the August 2023 Android Security Bulletin here.
How to get the August 2023 security update on your Galaxy S23?
If you own a Galaxy S23 device, you can check for the August 2023 security update by going to Settings > Software update > Download and install. Alternatively, you can download the firmware from Samsung’s servers using tools like Frija or SamFirm and flash it manually using Odin.
However, before you proceed with the update, make sure that your device has enough battery life and storage space. You should also back up your important data to avoid any potential data loss or corruption.
What about other Samsung devices?
The Galaxy S23 series is not the only Samsung device to receive the August 2023 security update. The company has also rolled out the patch for the Galaxy S20 FE, which is a popular mid-range flagship from last year. The update for the Galaxy S20 FE is much smaller in size and does not seem to contain any new features or changes.
Samsung has also updated some of its foldable devices with the August 2023 security patch, including the Galaxy Fold 4, Galaxy Flip 4, Galaxy Fold 3, and Galaxy Flip 3. These devices were launched recently at Samsung’s Unpacked event with One UI 5.1.1, which is a minor update over One UI 5.1 that runs on the Galaxy S23 series.
Samsung has not yet announced when it will start its One UI 6 beta program based on Android 14 for its flagship devices. However, some rumors suggest that it could happen sometime this month. One UI 6 is expected to bring a major overhaul of Samsung’s software design and features, as well as Android 14’s new enhancements.
