I'm trying to learn where everything is. 1st my stylus came out & lost it. Also, I got a 256 gb sd from 128. I create a folder for all my photos on sd card. Seems they disapear. Im so frustrated. Isnt it better to do this? Making ph run smoothier? I know not necessarily as iphones done even have a slot for 1. I just got this phone Christmas week. How to smoothly run note 8. I really want note 9. Is there a big diff? We got it pre owned?
