And starting this month, those who purchase certain Samsung devices will find access to Dropbox through core apps on those models. One of those devices offering such integration, will be the Samsung Galaxy Note 4. The default mobile document reader on the phablet will allow you to save your document to Dropbox with a single tap.
The advantage of using cloud storage is that it opens up the space on your phone, once you move your content into the cloud. The Samsung Galaxy Note 4 has 32GB of native storage and offers a 64GB capacity microSD slot. The extra cloud storage will be quite welcome by Galaxy Note 4 owners.
