Galaxy S25 gets mysteriously huge, 1.2GB software update

After releasing the May 2025 security patch to the Galaxy S25, Samsung has released a new and mysteriously huge software update to it.

You might think it brings a new security patch to the devices in the lineup, but it doesn't. It still uses the May 2025 security patch, which means the update might include several bug fixes and performance improvements. Or, it could very well be the pre-One UI 8.0 update.

It still uses the May 2025 security patch.

Once the update is downloaded completely, tap the Install now button to start the installation process, and the phone will then restart after a few minutes.

You can also download the firmware file from SamMobile's database and flash it manually using a computer running Windows OS and Odin tool.

This software update could be released in other regions and countries over the next few days.
