Dear sir,
I am using red mi note 4 mobile,
I got ui version,
But some others got and
And one more thing till we are running android 7 but others using pie version.
Must you note one point,,,, in India u launch note series note 3 and note 4
They are very popular and best selling phones in universal,  and your company going to high position and given tough competition to other mobile companies.
This total credit goes to note 3 and note 4 mobile's . I strongly believe these two phones mother of the xiomi in India.
But now you neglect the these two phones.
So pls don't show partiality.
Thanking you.
