I have the Nexus 5 mainly because it is a pure Android phone. It was great that my last phone S3 has an option to switch an extended battery out off MPJ though; I haven't really had to do that on Nexus 5 so far. However, I like to have a lot of data on my phone, so micro SD is pretty important for me. Have no idea why it doesn?t has micro SD slot Anyone is also running in to problems because of micro SD or non-removable battery?
