Google has warned users running the latest stable version of Android not to install preview builds of Android 11 on their devices.

The June 2020 build of Android (build QQ3A.200605.001) was released earlier this week, although only those running Google’s own Pixel smartphones will have received the update at this stage.

However, Google is urging those customers not to install the developer builds of the forthcoming Android 11, suggesting it could have dire consequences for the user’s phone.

“If you want to install Developer Preview 4 on a device running the Android 10 June 2020 update (build QQ3A.200605.001), please note that sideloading the DP4 OTA images on this page will not work properly and could cause device issues,” Google warns on its Android Developers blog. “To install DP4, you can flash an image from the downloads page instead.”

Flashing an image requires users to completely wipe their phone, rather than update in place, which keeps files and compatible installed apps intact.
