Model- Yureka note yu 6000, it is a good phone with good processor but there are many disadvantages too in this phone. It gives u only 2 slot for memory card and sim card.there is a option in second slot that to use sim card or memory card, due to this we are unable to use 2 sim cards in a phone. This phone contains unremovable battery, it means it does not allow to remove battery from phone, the biggest problem of this is that if your battery deatroys you can’t change by yourself it has to send to the service center after that it will take a long time to return back. : -(
