Samsung extends May 2025 security update to Galaxy S21 FE

The Galaxy S21 FE’s Android 15-based One UI 7.0 update, despite being released this month, came with the April 2025 security patch.

Well, the brand has now started rolling out the May 2025 security patch to the smartphone, which fixes the issues mentioned here.

At the moment, Samsung is offering the update only to the factory-unlocked version of the Galaxy S21 FE, which has the model number SM-G990U1. It carries firmware version G990U1UESGHYE5. The update is live for devices on most networks, including AT&T, Bluegrass Cellular, C-Spire, Cellular South, Cricket, Comcast, DISH, MetroPCS, T-Mobile, Tracfone, Verizon, and Xfinity Mobile.

To update your Galaxy S21 FE to the May 2025 security patch, go to Settings » Software update » Download and install, or head to our firmware section, download the firmware, and then, using a Windows PC with the Odin application, install it manually on your device. We expect Samsung to roll out the update to other variants of the device in the next few days.

Samsung is also developing Android 16-based One UI 8.0, and the Galaxy S21 FE is eligible to get it. Earlier this week, the brand opened its beta program for the Galaxy S25 series. However, there’s no information about when the company will release its stable version. If you have a Galaxy Watch, you might take a look at Samsung’s upcoming Wear OS 6-based One UI 8 Watch.
