Amazon, just like Google, has its own online photo storage service that is called Amazon Photos. With its Android application you've got up to 5 GB of free space, unless you're a premium Amazon user, in which case you're entitled to unlimited storage.
Automatic photo backups
You'll no longer have to worry about losing or damaging your smartphone, because all your photos will be automatically uploaded to Amazon's cloud, from where you can organize them all into albums or following a timeline.
Furthermore, you can also edit your pics straight from the application, from where you can also share them with your friends on social networks or via direct links. Don't hesitate, move over to Amazon Photos to have all your pics in a safe place.
