Samsung had started rolling out the May 2021 security update even before the month had started. The company released new software updates for 350 devices (including variants) during that month. Now, the South Korean firm has released a new security update to the carrier variant of the Galaxy A51 in the US.

The Galaxy A51 (SM-A515U) has started receiving a new software update in the US. Currently, the update is available on Comcast’s network, but could soon roll out to Sprint, Verizon, and Xfinity Mobile. The latest software, which features firmware version A515USQU6CUE2, includes the May 2021 security patch. This update fixes various privacy and security-related vulnerabilities within the Android operating system and Samsung’s One UI software. As per the documentation, the new software includes dozens of fixes from Google and 23 fixes from Samsung.


If you own a Galaxy A51 on Comcast’s network in the US, the new update might have arrived on your smartphone already. If it hasn’t you can check for the update manually by navigating to Settings » Software update and tapping on Download and install. You can also download the entire firmware file from our firmware section and flash it manually.

The Galaxy A51 was launched in December 2019 with Android 10 on board. The phone received the Android 11-based One UI 3.1 update earlier this year. It is expected that the phone will receive one more major Android OS update sometime in Q4 2021 or Q1 2022. The international version of the Galaxy A51 (SM-A515F) had received the May patch one month ago.
