New Hdr Doesn't Work! Redmi Note 2

Jan 7, 2015
Hy guys,
Today I updated my Redmi Note 2 with the last weekly release. After that I notice that, when I made photos in HDR mode, camera actually doesn't take HDR photos...I know that because there are no differences between photos made in Auto mode and in HDR mode. Then, I don't know if it happens only on my device, but when I take a photo in HDR mode, camera is really fast (and this is strange, because an HDR photo needs a longer time). Help guys!!!
