Both phones running Android. Samsung: Android 4.1.2; LG: 5.0.1
I use gmail, so I expect my contacts and email should transfer to the new phone.
However, that leaves:
text messages (I've been using the default messenger app)
photos (I don't get how the gallery app seems to be a collection of numerous locations e.g. Camera, download, Bluetooth, DCIM, Facebook, Instagram, PicsArt, Viber Images, WhatsApp...
I'd like the text messages and photos to behave like gmail: transparently available from whatever device I use (will dropbox do that? I saw someplace people were using gmail account to automatically backup text messages too, but that seemed more like a "backup" instead of being transparently accessible from any device? Will Hangouts for text do it?)
