As I tried to read my emails the other day, my phone kept telling me that I had no more space and that I needed to delete files. So I hooked it up to my computer and.... I had barely any memory left at all. All the photographs that we enjoy taking and sending to each other, they all end up in there. And once in a while we need to download them to a hard drive or store them in the cloud and delete them. It took me more than 30min. Anything to do with electronics always takes longer, at least for me, but I can read my emails again! :-)
I hear so many people say, talking about their phone; "I have my whole life on this!"
Back up your phones! Save your contacts on google! Download your photos! The day you break your phone, loose it or have it stolen, it will be an annoyance but not the end of the world...
