This phone is waste of money.Radio/antenna problems, calls /sms works occasionally.Perfomance is not so good.There is no suitable ram given by the samsung brand.Even its difficult to run lite version of the softwares properly.
Hardware is not enough to support the features of the OS.The phone is much slow to respond eg opening closing apps, launching keyboard even opening contacts to make a phone call it takes at least 30 seconds.The storage is less.
