I have been using Lenovo k4 note with 3gb ram and 16 gb internal storage. It is a nice phone but recently there is a drop in its performance due to the unupdated Android. But it’s been with me for past 2 years and I find it as a nice and useful mobile for me.
It is not at all good for big games of more then 1 gb .
Nice music experience with dolby audio speakers.
Good for movie, music and professional applications!
