Photos and videos. Keep them safe.
SAFELY BACKING UP PHOTOS/VIDEOS AND FREEING UP SPACE ON YOUR DEVICE
For many, photos and videos are the most important items on your phone. Here are two apps that allow you to back up the photos and videos on your device and let you safely remove them to create more space.
1. Google Photos: If you have a gmail account, you have unlimited cloud storage. The unlimited option does compress your files slightly, so save originals if you want to make prints.
2. Flickr offers 1,000 GB of free storage. No file compression.
