Statement of Third-party Applications

the third-party applications, rather than the phone itself.
The installation of a third-party ROM or non-official operating system might bring
security risk and security threats. Nubia Technology Co., Ltd. shall not be liable for
the security threats brought by upgrade of the operating system.
