The Galaxy S21 series was launched in January 2021 with a promise of 4 OS upgrades. As per this, the phones are eligible to get the Android 15 update too.

Anyway, with that out of the way, let’s just get into downloading One UI. Ensure your device is backed up before you flash the new update. Also, make sure the device has sufficient charge and a stable Wi-Fi/mobile data connection.

Once those prerequisites are met, follow these steps:

Step 1: Go to the phone’s Settings
Step 2: Tap on Software Update
Step 3: Tap on Download and Install

It will take some time to download and install the update. The device may even reboot in the process. Once it is done, you will see that “Your device has been upgraded to One UI 6”.
