Redmi Note 8 2021 stable update: first published on June 17, 2021. Check below for latest releases…

The Redmi Note 8 2021 is a refreshed version of the 2019 version of the device. A couple of weeks ago, the company announced it sold over 25 million units, making it the best-selling Redmi Note phone. That probably triggered the release of a 2021 version, but given that the specs are almost the same, it might not be a success again in 2021. Notwithstanding, the company is currently rolling out a new Redmi Note 8 2021 stable update in multiple regions. It’s a build that bumps the security patch level to May 2021 to increase system security and stability.
