The samsung galaxy note 3 neo is best in 20000. I have used more than one year . It has some cool features.
Pros:
It is 5.5 inch mobile which is comfort in hand. The display is awesome because of amoled display.
It has 3100 mah battery which does a really good job. More than 1 full day . The screen on time is good . I have hot around 5 hr .
It has a s-pin which is a cool feature in jote series.
It has 8mp back camera which does a good job and 2mp front camera took good selfie and pictures.
It has no heating issue I found. maximum temperature I will got 42 degree. . Which is not very hot .
The gaming performance is good I say. No lag I found.
Cons
Only one cons is the design the metallic paint is damaged after using the device and some time it will wait some time to wake up the screen and the application. My opinion this is best . in 20000 . Samsung does a really good job .
