Huawei has released the January 2023 software update for the Huawei Nova Y90 and Y70 smartphones in the global market, and this firmware clearly improves these phones’ security aspects for a better user experience.
Both Huawei Nova Y90 and Y70 runs EMUI 12 out of the box but it would be interesting if the company could have sent EMUI 13 instead of the security patch. Speaking of which, no one knows, when Huawei will rollout EMUI 13 for global users for the time being.
Coming back to the rollout, January 2023 security update for Huawei Nova Y90 and Nova Y70 comes with EMUI version 12.0.1.177 and EMUI 12.0.1.202. This update is suggested to install on all of the devices sold marketed outside of China and will appear in batches.
We suggest the corresponding users look into the settings > then open System & updates, followed by a Software update, and then tap on CHECK FOR UPDATES. You can download the latest firmware also from the My Huawei app.
You should know that the update won’t erase your personal data but it is suggested for you back up any important data before updating the device. On the other hand, the package will be deleted automatically once the installation succeeds.
