Is Honor 20 eligible for EMUI 12?

The Chinese counterpart of Honor 20 is currently running on HarmonyOS 2.0 software system while the global variant is on Magic UI 4. To be mentioned, the Honor 20 series is performing well with the HarmonyOS system, which means these smartphones have capabilities to support the latest softwares.

So, it is expected that soon or later these smartphones will get the hands-on new OS but we’ll have to wait for an official confirmation. However, EMUI 12 beta testing is just started so it may some time to reach old smartphones.


Before upgrading to the latest version, Honor 20 users, we recommend you to take a backup of your important data to prevent data loss. However, the update doesn’t erase your data but it’s good to take a backup. Also, maintain enough battery and storage on your device.
