K3 note win hand down on Honor 4X.
Better screen, Lighter, Newer OS (Lollipop), Much better CPU performance.

Mi4i for normal use is good cause got 5" screen. For gaming Mi4i overheat......very hot. Not only gaming....use gps, suftnet etc also heating. Thats why i m waiting for K3 Note and it is 5.5" screen...good for gaming.
K3 Note....someone tested on gaming here? Got overheat?
I know is mediatek 64bit but if snappy 64bit much better

My best guess is about the same. If you want better camera, you should buy Mi4i. Many reviews said the camera in Mi4i perform well for it price range.

LOL....Here map issue solved after i change my microSD card from 32GB to 64GB. Can transfer apps and map to external Sdcard
This K3 Note is very good base on this price. Much much better than Xiomi phone.

I kenot brain by changing sd card frm 32 to 64gb make ur HERE map works ???
Yeah why pay >700 for mi4i / m1 note / zenfone if u can get better deal with this hp at price below 600...
With frequent updates frm vibeui team, this hp is perfect...

It's subjective, depend on individual taste...
