Pretty worrying and scary !!
A Xiaomi Redmi Note from Hong Kong made a bold claim (with proof) that his device is connecting to a Chinese IP address and frequently sending personal data such as photos and text messages over to the Chinese server, without any user consent whatsoever. This is a serious allegation, and it looks like it is 100% legit.
The data transfer takes place when the Xiaomi Redmi Note is connected to a Wi-Fi network. The user tried rooting his phone and flashing a different firmware, but the data transfer still took place regardless. A little digging up revealed that the IP address belongs to CNNIC.
