Xiaomi was banned over patent issues for like a week before they resolved it. The issue you are referring to, the Indian Air Force "warned" the use of Xiaomi devices because they tracked them uploading data to China. Xiaomi responded with an update which had one-click Mi Cloud turn off switch to stop that from happening. They were uploading meta data for their cloud services just like any other company. Xiaomi also announced a new datacentre in India to mitigate this concern. But they never got banned over this. Xiaomi sold less than 2 million devices in India in 4-ish months. But to put things in perspective, they sold 8-9 times more than Google's Android One phones, another program targeting the same market. They sold the flagship Mi3 only for a couple weeks and then continued selling lower end device. They are launching Mi4 here this month, so that number will now probably go higher.
