Samsung has already introduced the One UI 6.1 update to many Galaxy devices, including the Galaxy S24 series, and the latest flagship device is also grabbing the May 2024 security update, which is limitedly available in some locked units. Now, the company has started rolling out the update for the unlocked variants.

Notably, the unlocked units of the Galaxy S24, Galaxy S24+, and Galaxy S24 Ultra have started receiving the May 2024 security patch update with the firmware version numbers S921U1UES2AXD3, S926U1UES2AXD3, and S928U1UES2AXD3, respectively. With the latest update, you will not see any significant change, but it will surely enhance the internal mechanism.

Samsung’s May 2024 security patch addresses more than 50 fixes

According to the official documentation, there are more than 50 fixes introduced, and Google has added 31 fixes that improve the internal functioning of the device and aim to improve the security mechanisms of the devices. Along with this, Samsung has also brought 25 more patches that exclusively enhance the internal mechanisms of the Galaxy devices.

Additionally, if you are having any issues with past software updates, then you should try the latest security patch, which may provide some additional improvements for the devices. It may also boost the performance and stability of the devices.

If you are using the unlocked variant of the Galaxy S24 devices in the US, then you can now install the latest software on your device by simply going to the software update manually from the system settings.

The Samsung Galaxy AI feature has brought a revolution to Galaxy devices. With its introduction, the company has been successful in creating a strong image of innovation, and we have also seen the results where it has achieved record sales of its latest flagship devices, i.e., the Galaxy S24 series. Then, to provide these features to the older devices, it has expanded the One UI 6.1 update for other devices; however, the company has only provided two features for the devices released back in 2021.

Galaxy S21, S21+, S21 Ultra, Fold 3, and Flip 4 have Circle to Search and Chat Assistant AI Features of One UI 6.1

Samsung has recently introduced the One UI 6.1 for older devices, including the Galaxy S21 series, the Galaxy Z Fold 3, and the Galaxy Z Flip 3. For these devices, the company has only introduced two Galaxy AI features in the form of Circle to Search and Chat Assistant.

Circle to search: The Circle to search feature allows users to instantly search for information about the images that appear on the screen with convenience. The circle-to-search works on the same principle as Google Lens, but to make it more appealing, the company has made accessing the feature simple. This means you can easily search the objects by incircle after pressing the home button or navigation bar.

Chat Assistant: Chat Assistant is another innovation that improves the user experience of conversation. The feature dedicatedly provides translation in 13 languages with Samsung’s original keyboard.

Meanwhile, other flagship Galaxy devices, which were launched in 2022 or later, have received several other Galaxy AI features, including browsing assistance, live call translation, note assistance, and many more. However, it may be possible that some of these Galaxy AI features may arrive for older devices in the next major update.

Samsung has started expanding the One UI 6.1 update in the third phase for the older devices. Initially, it has rolled out the update for several Galaxy devices, including the Galaxy S22, Galaxy S21, Galaxy Z Fold 4, Galaxy Z Flip 4, Galaxy Z Flip 3, and Galaxy Z Fold 3. However, the company hasn’t brought the update for the FE edition of the devices at the time. Fortunately, Galaxy S21 FE users also get a taste of One UI 6.1 features in the US.

Carrier-Locked Galaxy S21 FE gets One UI 6.1 update in the US

Samsung Galaxy S21 FE is spotted receiving the update for the locked version in the US. More specifically, the update arrives on some carriers, including T-Mobile, MetroPCS, US Cellular, and Dish Wireless, with two different models with firmware version numbers G990USQUAGXDG and G990U2SQU8GXDE.

One UI 6.1 update without any Galaxy AI features

Samsung has brought the One 6.1 update with several features that offer customization related to the lock screen, alarm, calendar, and many more for the Galaxy S21 FE, but it hasn’t introduced the revolutionary innovations with the absence of Galaxy AI features, which has leveled up the user expertise in the field of providing convenience for the users. Even the Circle to Search feature available in the main Galaxy S21 series has not arrived for the fan edition.

Installation

Samsung Galaxy S21 FE (locked) users in the US can now update the device to the latest version by following these steps: First, go to the settings, then tap on the software update menu. If it shows a new update available, tap on the download button. If the update hasn’t arrived on your device, don’t worry; it will be soon available for you.
