Speechless. Review on Dropbox

A year before I accidently installed a software named as Dropbox and just turn on automatic upload toggle on . I just forget about app and gotted busy in daily shedule. I have samsungs galaxy s3 which is so powerful phone at that time , but sometime it get stuck . One day it deleted my all data and says welcome to samsung.??I dont know that my phone is resetted but how. So I login with my email address and click on playstore to install daily stuff app like whtsapp and fb and all and I also installed Dropbox and login that also. and Seeing my all photos back . I was surprised and amazed wow without doint anything my all data photos and documents where saved . I just connected my phone to my friends wifi network and downloaded all my data . So it is very good and very fast. Its app has nice user interphase and a good security system that no one can login from the app and see all the stuff that you have saved . So if you are searching a online data storing app then definately download this.

Thank you . ??
