Why the hell would you ever take your SD card out of your phone? Esp. when you have to take the battery out of your phone to even get to it.
Why not?
It's much faster to just set up a WiFi file sharing system or even use the USB cable to transfer files to whatever PC you're trying to put the media onto.
It depends on how much data you transfer.
The read/write speed on the G-Nex's internal memory would probably a bit faster than the transfer speed of any SD card, making file transfers pretty fast.
Since you have been given out false information in the past, I wonder whether you get any proof to support your statement.
I don't even know how you would keep track of multiple MicroSD cards either. I can be holding one and it will disappear like a friggin Chris Angel act.
I am not stupid.
