storage card removal
 

I am not using my storage card for installing apps nor for swapping. It is being used for audio, video, and picture storage. I have another card loaded with mp4's. Is it okay to just eject the current microsd card and put the other one it while the phone is on or do I need to turn the phone off first?

go to settings>sd card & phone storage>unmount sd card thats the safe way of doing it
