If you still transfer photos and videos from your phone by emailing them to yourself or hooking a USB cable from your phone to your computer, wouldn't it be great if your phone could automatically sync media files with your computer? If your phone breaks or gets lost before you transfer all of your photos and videos, you'd lose precious moments that you'd captured for posterity.
Dropbox offers 2 GB of free space and opportunities to earn additional free space. Set up a free Dropbox account, then download the app from the Google Play Store. Next, go through the initial setup on your device, telling Dropbox to automatically upload photos and videos. You may want to have it execute transfers only over Wi-Fi, since uploads could quickly drain your monthly mobile data allotment. Large media uploads can also drain your battery, so you may wish to manually turn off auto-uploads when you won't have a charger available for awhile.
Google Drive also offers easy to use cloud storage, giving you a whopping 15 GB of free space. Auto uploads of photos and videos take place through a simple setup with Google Plus, though you don't ever need to share your photos on Google Plus unless you want to.
Both Google Drive and Dropbox offer free Windows software for you to install on your computer, so your photo and video files sync will sync there, too.
