Re: where do my pics go when i save them in a cloud
Once you save your photos in the cloud you can delete them locally in your phone to get some free space. You'll be able to access those photos from different devices through your account. I like using Google Drive and Dropbox, but there are many different options.
If you decide to use one of them take your time understanding the sync settings. This is important and will avoid using a lot of your battery with unnecessary back ups.
