Sound Quality is too good to here on earphones as well as on speaker.
The UI is best one to get connected with what you want, only one drawback is that you cant sort application name wise.
Style and Design is OK.
Can set data/wifi connection as you needed, for each app using iManager.
Good Screen, but sometime its difficult to handle, but the mini screen feature helps for one handed use.
14 K might be sufficient for this phone.
As per the price range it does not include infrared which you can get in cheaper Xiomi Mi phones.??
