So dropbox is a cloud service which let’s you store your photos videos and other documents to the cloud. Whenever u require them, u will need to log into dropbox first either through your computer or your cellphone and then u can have access to your photos. It provides you with a Maximum storage space of 2GBs free. And rest u will have to buy.
I was using dropbox since last 2 3 years. I used to save my all my photos and videos to dropbox so as to ensure their safety. I can’t save them in my phone because of limited storage and moreover I have to reset my phone atleast once a month. So dropbox was my fav destination. But a while ago when I checked my previously uploaded videos, I couldn’t find them. I uploaded near about 263 videos in total but now there are only 12 left. Most of my photos aren’t available too. I even complained them but it was of no use. According to them they are not at fault. This is the worst app.
If u really want to save your photos to a reliable cloud service you can use shoebox instead. The cloud storage offered to you over there is unlimited. Go for it.
