Xiaomi note 4 may not be described as a true sucessor of its previous flagship Xiaomi Note 3 but when you use the phone yourself will find that the phone is awesome and works charm.!
Pros:
Sound clarity is better and loud.
Phone design and make looks premium
Multitasking is good with the 2Ghz processor
Quick upgrade to Nagaout is wonder.
The FHD screen looks brilliant and angles are better.
Infrared and Dual sim LTE
Cons:
Camera pics in low lights. Previous version had the same issue.
Sound output is at bottom so if you phone is in jeans you need to keep it upside down.
Hybrid sim slot. No wonder all the recent phones within budget comes with it.
No freebies like screen protector or back case.
Ultimately buying this phone is still worth money spent.!
Thanks
