Longtime iPhone user, first time with android. I've always used iTunes (iPhoto) to backup my photos. What do you all use to backup your photos? I guess as a side note what do you use to backup music? I'm really unclear as to what gets backed up where automatically was well.
Thanks in advance
Welcome to the forums. Photos can get backed up to almost any cloud service of your choosing. Google can back them up in the Photos app, or they can be sent to Box, Dropbox, etc..
Music doesn't really get backed up. You can upload all your music to Google Play Music from your desktop, and then stream or download a copy.
The other things that get backed up are your contacts if you have them saved to Google servers. I believe they can be saved on Samsung servers as well (been a while since I have had a Samsung, and I didn't user their services), while most other things, like Calendars and such depend on who you back them up to. Samsung is a possibility, along with Google.
