I have this phone with 3 gb ram and 32 gb internal varient. It is working smooth. But 4gb varient works awesome . I dont think this phone ever hang. Its camera is working awesome . Its screen is boggest in all mi phones i think. Its large display helps to read documents or books easily. And it has long live battery with 4000 mah. Which gives 2 day battery backup. But sometimes this phone heats when i use it with charging. So this is a disadvantage of this phone. Overall in my experience with this phone. Its awsm in 10k range......
