I have bought redmi note 4(3gb ram and 32 gb internal memory) last week . I can say that xiamoi is disappointing me again . First diadvantage is its poor camera , it clicks average pictures in day light and worst picture during low light . Another disadvantage is the absence of external memory card slot, I dont understand why the manufactures are making the device in this form . 4k video recording is also not possible with the primary camera which is another cons .
