Xiaomi India has posted in its facebook page that Mi4 16 gb model will give away its registration model and enter in to an open sale model. I guess this is in the backdrop of muted response that Mi4 16 gb received in its previous sales.

Make no mistake Mi4 is pretty good device, But with Lack of 4g and Micro SD card slot, the 16gb version had few takers. Given that there are other cheaper options such as Oneplus One and Honor Holly 6. There is also consensus between Bloggers and fans MI4 was priced a tad higher which made it loose its appeal.
