Hi.
Friends
I have been using the yu yureka black mobile from last 4 mnts and till now I have not finded any error or bugs in it and also it has a volte network which is also very good for 4g networks such as jio can be runned perfectly on volte.in my area I cannot find any customer service center for yu yureka that was disappointed me very much.it is a value for money phone. I liked it very much
