RedMi Note.
Earlier, member Kenny Li on the IMA Mobile forum in Hong Kong found that his RedMi Note connected to an IP address in China and transmitted data to it whenever Wi-Fi was turned on. This phenomenon does not happen with 3G connectivity and according to Li is to avoid user attention. Initially, he thought the device was only updating the firmware, but the surprise was that even if Li had rooted (interfering with the system) on the phone and changed to another firmware, the underground data exchange would still take place, testifying This process has been integrated deeply into the machine.
The RedMi Note along with Mi-3 are Xiaomi's two smartphones that are widely sold in Vietnam, most of which are imported directly from the Chinese market, but there are also a number of machines from Hong Kong, where users discover the phenomenon of automatically sending the above data. The owner of some portable stores confirmed that if there were information that the machines were sold in Vietnam, the spy-type phenomenon would not continue to be sold.
