i want to know how my old pictures, contacts, music, etc, can transfer onto my new phone.
Go into settings and scroll down to your accounts and select Google, then tap on your Gmail address and it will give you a list of what you want to sync just check off the ones you want to sync to your Google account then tap the sync now option and wait till each spinning icon finishes. There all that stuff is synced to your Google account. If you have a Samsung device you can tap on your Samsung account and repeat the process. There's some things that sync to Samsung cloud that Google won't do and visa versa so it's best to check out both if you have a Samsung device.
