As someone who uses over 75 phones in any given year, I rely on Android's data transfer feature extensively. By now, setting up a new phone is second-nature; it takes me just under an hour to move data, and it's about as seamless as it gets. While the underlying transfer system hasn't changed too much, Google made a few tweaks last year that makes moving to a new phone a little easier.Whenever you're setting up a new phone, there's a QR code that lets you share your home network details easier. But the change that I like the most is the percentage indicator that shows up when you're actually transferring data from your old Android phone to your new one. I'll admit that it is a small thing, but I found it to be quite useful; Google rolled out the change a year ago, and it has made quite the difference when setting up a new Android phone.
