How do I set up my Samsung Galaxy Tab 4 to automatically upload photos to Google+?
When you add your Google+ account to your device you can set your device to automatically upload your photos and videos to Google+.
Setting up a Google+ account
If you don't already have a Google+ account you'll need to sign up for one here. Follow the instructions to register for Google+ and then proceed through the steps in the following sections.
Setting up the Google+ app
1. To open the Google+ application touch Apps
> Google+ 
2. If you have not opened the Google+ application previously
then select the Google account to which to upload
files.
3. Select the desired Google+ settings for Contacts and then touch Next.
4. You will then be prompted to enable Auto-Backup. Select
Over Wi-Fi or mobile network or
Over Wi-Fi only as the preferred means
to upload files. If you're concerned about incurring extra charges from
your mobile network, or using up too much of your mobile data allowance,
then we recommend selecting "Over Wi-Fi only".
5. Touch Done to continue.
If you need to modify the Auto-Backup settings follow the steps below:
1. To open the Google+ application touch
Apps 
> Google+ 
2. Touch the More options icon 
> Settings > Auto-Backup.
3. Touch the
switch 
to turn Auto-Backup on 
4. Touch the various Auto-Backup options to alter them, enabling you to change what is uploaded to the cloud and when.
Note: when you enable Auto-Backup of your photos
and videos to Google+ they are set to private and will not be visible to
anyone in your Circles until you choose to share these files.
