Highlights tab See uploaded pics ANDROID TIPS
Unlike the Camera tab, the Highlights tab is the point of call in order to view the photos that have been uploaded to your Google+ account.
Note that these could have arrived from friends or uploaded from other devices such as the desktop or iOS platforms.
If you select a thumbnail image directly from the Highlights tab, you will see that the image has a small icon at the bottom (a little wand symbol); this indicates that it has been enhanced.
You can actually tap this to remove the enhancement and return to the original picture or repeat the option to put it back on. A press of the Menu button at the top will also allow you to delete the image or set it as your home screen wallpaper.
