Yu yureka from micromax is the real best when it comes to performance and packs a powerful snapdragon chipset, 1.7 ghz octa core processor which gives you a smooth using experience. It packs a 2 gb ram which helps you to do multitasking with ease.
One more feature is the cyanogenmod os. It is the customised rom from cyanogen and amazing features are included in tha pack. This device’s price is also an amazing part as it is of only 7999. If you are searching for a budget phone then I would recommend you to buy this. There is also a flaw in the device that it gets heated a little more on playing game, and that is because ot packs a powerful processor.
