Microsoft Lumia 640 have 1 GB ram and 8 GB external memory. This mobile phone is very easily to use compare as other androids . Store of this phone is very fast compared as other mobile phone sound of this phone is very clear in this phone ms office is also available OneDrive etc this phone is very useful
Disadvantage: Disadvantage of this phone is his front camera is 1 mp when we have shoot pic then the picture is not good clearly. Another disadvantage of this phone is some time phone is hang . When we have to restart then remove tha battery first.
