After a long time, Xiaomi is all set to launch a smartphone based on MediaTek Chipset quite soon in India. The company was earlier banned from using MKT chipsets after a lawsuit filed by Errisson. David Ku, Chief Financial Officer, Mediatek,  said to The Mobile Indian, “ The lawsuit filed against Xiaomi by Erricson is a history and now the things have settled down. Xioami is now free to use our chipsets.”

He added, “ Xiaomi will launch a smartphone based on our chipset in India pretty soon.” He didn’t divulge any further information pertaining to the processor but it is expected that Helio P22 may power a new smartphone from Xiaomi. In 2014, Ericsson had filed a case against Xiaomi for using some patents without taking permission from Ericsson, those were the same patents for which Ericsson had brought Micromax, Intel and some other companies too in court.

Xiaomi’s last device with a MediaTek SoC was the Redmi Note 4. It was released in August 2016 only in China market. If some of the latest news leaks are to be believed Xiaomi has placed orders for the new Helio P60 and P70 SoCs built on TSMC's 12nm manufacturing process.
