Notes and Constraints

Notes

• Do not use Huawei Cloud resources for black market or perform activities that violate laws and regulations or Huawei security requirements. If you violate related requirements, your accounts will be restricted or frozen.
• When your Huawei Cloud account is restricted or frozen or your cloud phones are retained, the use of cloud phones will be restricted. You need to handle these issues in advance to avoid service interruptions.
  • If your Huawei Cloud account is restricted due to insufficient balance, you cannot perform operations such as restarting cloud phones and changing images or pushing files for cloud phones.
  • If your Huawei Cloud account is in arrears and frozen, you cannot perform operations such as restarting cloud phones and changing images or pushing files for cloud phones.
  • If your cloud phones enter the retention period because they are in arrears or have not been renewed upon expiration, the cloud phones will be frozen and cannot be used.
• Cloud phone servers of the physical.kg1.4xlarge, physical.rx2.32xlarge.4, and physical.rx3.32xlarge.4 series use pay-per-use Elastic Volume Service (EVS) disks for storage. Fees are charged by hour in real time. You need to ensure that your account balance is sufficient to prevent resource freezing caused by account arrears.
• You need to keep the access key of the cloud phone secure and exercise caution when selecting the open access port of the cloud phone to ensure security.
• Cloud phone severs of the physical.rx1.xlarge series use local disks to store data. You can periodically back up important data.

CPH Constraints

• A cloud phone server runs the native Android OS and has virtual phone functions. It does not have carrier service attributes and does not support functions such as virtual SIM cards, making calls, and sending and receiving SMS messages.
• Cloud phone servers support only the native Android OS. You cannot change the OS or OS type by flashing a ROM or other operations.
• Cloud phone servers do not support secondary virtualization. That is, virtualization software cannot be installed on cloud phone servers.
• Cloud phone servers do not have built-in screenshot and screen recording tools.
• Google Mobile Service (GMS) cannot be installed on cloud phone servers.
• Cloud phone server specifications (for example, Quantity) cannot be changed unless you unsubscribe from the current server and purchase one that meets your requirements.
• Cloud phone servers do not support service data migration between different regions or accounts.

AOSP 11 Image Constraints

AOSP 11 images include CPUI 1.0 (for Chinese mainland) and CPUI International 1.0.

1. AOSP 11 images cannot be used by the root user.
2. The system disk of an AOSP 11 image is read-only. Files on this disk cannot be modified or deleted.
3. adb shell cannot be used to modify an attribute whose name contains ro.
4. appctrl and application sharing are not supported.
5. CPUI 1.0 is available in Chinese mainland regions and does not support GMS. CPUI International 1.0 is available in global regions and is preset with GMS by default.
6. There are restrictions on changing images.
   • AOSP 11 public images can be changed with each other.
   • AOSP 11 public and private images cannot be changed with each other.
   • AOSP 11 public images and AOSP 7/AOSP 9 public images cannot be changed with each other.
   • AOSP 11 public images and AOSP 7/AOSP 9 private images cannot be changed with each other.
   • AOSP 11 public images (CPUI 1.0) and AOSP 11 public images (CPUI International 1.0) cannot be changed with each other.
   

   If no public images meet your requirements, you can create a private image. When purchasing an AOSP 11 cloud server, select the private image.

7. Attributes whose names contain ro cannot be modified. Only the com.cph.bandwidth_limit, com.cph.network.type, and com.cph.mainkeys attributes can be modified.
8. AOSP 11 public images are encrypted. To avoid data disorder, perform operations on cloud phones only after they are started.
