Be aware backup and sync will backup and sync your photos meaning, all the photos loaded in your Google will download into your phone and fill it up maxed out every time! Very frustrating! If I delete pictures or videos on my phone so I can save space and then delete them off of Google as well! Additionally there's no screensaver or slideshow that I can find for any particular album or all the photos. And the last time I upgraded to a new phone and transferred photos, albums were deleted
