A still rather obscure feature on the Xiaomi smartphone is the activation of "Get updates sooner", and it is strongly believed that a finished version will be made available for download that resembles a beta and may not have been tested sufficiently.

Note: Enabling this feature is not highly recommended as it may cause damage or malfunction to the phone, and may not work properly and destabilize the system.
