HMS Toolkit provides Cloud Debugging for you to perform 24/7 uninterrupted testing on your app running on remote real devices, covering a wide range of Huawei models. With this function, you can learn about the running status of apps on Huawei devices anytime and anywhere even if no device is available, device types are not completed, or an error cannot be reproduced, helping you build a better app for users.
Cloud Debugging allows you to use a specific device for 2 hours at most each time. Before the duration expires, you'll need to release the device and apply for the device again. When you use Cloud Debugging for the first time, a 24-hour duration will be allocated to you. When the duration expires, the system will automatically remind you whether to renew the duration. You can renew 8 hours at a time. You are advised to efficiently use devices and release idle devices in a timely manner.

- Cloud Debugging has been removed from the Chinese mainland, other regions in Asia, Africa, and Latin America since June 30, 2023. Currently, Cloud Debugging is available only in Europe and Russia.
