Within 20K budget Samsung Galaxy E7 is the most preferred phone.I have gifted it to my sister after lots of research.The phone has 5.5" screen with AMOLED display.
The picture quality of the camera is fabulous as the Primary camera is 13MP and Secondary camera with 5 MP.Also it has high speed processor with 2 GB RAM which enables the game proficiency.Internal Memory is quite good i.e 16GB.
Apart from all these it slim look and high battery back up with 3000mah pulled me to buy this and I amvery much happy with my decision.
Classy!
