Yu yureka is very powerful and we can say fast android mobile for specially hardcode mobile users. who want better experience of mobile gaming and dont want to spent much amount on mobile or looking for low price mobile then yu yureak is the perfect choice. It comes with cyanogen os so people who want customization. you can change or customize almost anything look and feel of ui of yureka, and now it got the update of lolipop verson 5.1 also so thats very good .
It comes with snapdragon610 processor and 2gb of ram and 16 gb of internal memory and can be expanded upto 64 gb so it is very powerful and never heng. but yaah stil there are one or two weak points are there, like bettry only 2500 mah so mostly in normal use, it descharged in single day. and on the time of playing high graphics games like asfalt 8 it get heated. so heating problem is there. but yaah at the end . I can say it is the best mobile because at this price they provide such a good camera and screen .
