The most notable difference is the overhauled icon set – the folder icons within the app have all been altered and now come with a more minimalistic and flatter design. What's more, the signature blue box of the Dropbox icon in the app drawer is now devoid of the massive white background.
Moving on from the design changes, Dropbox now makes linking a computer to your account a child's play. Thanks to the new Link a Computer option in the Settings menu, users can link with a PC in three simple steps. First of all, you have to visit www.dropbox.com/connect from the computer you want to pair with. A website with a certain QR image will be displayed and you have to point your smartphone's camera towards it. After the scan is complete, Dropbox will automatically authorize the PC. Voila, you are done!
