Seems like a mistake to me....
If... And I have a tendency to (on the face of it!), doubt that Xiaomi have... Or has anything that can beat off Samsung at it own Game. At the moment. Their stuff is only slightly cheaper. And for good reason. As a lot of the functionality that One has come to expect in Ones own Galaxy "Device" is sadly nowhere to be found on those cheapo Chinese Clones.
Xiaomi do seem to want to break out of that mold, and good on them for doing so too!
But, would you rather be known for producing valuable (But, affordable!), Goods... Or a purveyor in cheap tatty Headphones? As to their TV Market? I have to say I never knew they actually had One. Given how soft that market is though... I can't say I overly blame them for keeping them. That said, they should probably reconsider the Phones, if they ever want to actually get somewhere.
