New information about ROM updates for Clover Station Duo, Flex 2 and Mini 2


This announcement is only for developers who develop Android apps for Clover Station Duo (formerly Station Pro), Clover Station Solo, Clover Mini 2, and Clover Flex 2.

Change Notes

After our original announcement about Android 10 ROM updates, we heard from developers regarding the Build.SERIAL change and the need for more notice about ROM updates in the future. In response, we have taken the following actions:

  • After investigating mitigations for the Build.SERIAL issue, we have found a way to restore the old behavior by modifying the Android open source code.

  • We have created a new A10 ROM build and have done additional testing.

  • The new A10 ROMs will roll out to our sandbox environment on the evening of November 11 (Pacific time).

  • In the week starting Nov. 15, we will roll out these new ROMs to a limited set of production merchants. For all other merchants, we will roll out the new ROMs in early January.

  • When we roll out the new (patched) A10 ROMs, we expect existing apps to be compatible, and to work as normal with these ROMs.
    Please re-test your apps in sandbox next week, and let us know if you see any issues.

  • We are grateful to those app developers who have speedily patched their apps to no longer use Build.SERIAL. We encourage developers who have not yet done so to complete their changes as soon as possible.

  • We will revert our patch to Build.SERIAL in Q2 2022. Exact dates will be announced in future communications.
