When you insert a new sdcard the option pops up or you can go into the sdcard part and start the process.
You have to leave the card in THAT phone, it will not be read on other phone or pc once you format and configure it for phone storage.
As for large sdcard---ppl think they add to the speed of their phones like adding memory to a laptop.
They do not realize it is for saving info like a hard drive.
As for saving photos and videos to memory card...it depends on the photo/video app.
Go into the setup option of the app and you should see the option for location storage.
@NFQ and others... I would like to setup the option to autosynch my photos/videos over to my pc/nas. Not sure if I can set it to copy and check with what is on the phone, meaning as I delete things on the phone, only the saved items on the phones moves over. I don't want the pc/nas sending back stuff to the phone.
What app or setup to use for this? (don't say Tasker)...is it an easy IFTTT setup?
