Overview

For debugging and internal testing, you can install a HarmonyOS app or atomic service to a specific device. For security reasons, the device must be registered in AppGallery Connect. Each account is limited to registering a maximum of 100 devices per year.

Even if you delete a registered device within the year, it will still count towards your annual device limit. A deleted device is only automatically cleared from your quota, and no longer counts towards your annual limit, once a full year has passed since its initial registration.

You can also re-add a deleted device within the year. In this case, the device's registration time will remain its original registration time, not the re-addition time.
