Both devices were originally scheduled to start arriving on March 11th. But as it turns out, there will be some lucky T-Mobile customers rockin' the latest and greatest from Samsung earlier than they could have dreamed. Samsung listened to feedback from users and added back the dust and waterproofing feature that was on the Samsung Galaxy S5. Besides the IP68 certification, Samsung has returned the microSD slot that disappeared on last year's model.
If you received a notification about the shipping of your new Galaxy S7 or Galaxy S7 edge, now comes the fun part where every knock on the door elicits screams of joy. And the return commute from the office becomes exciting as you look forward to holding the new device in your hand. Of course, there could be a let down when you realize that the package on your doorstep is only the new Time-Life CD collection you've ordered ("Great Boy Bands of the '80s"). But once the let down feeling dissipates, the excitement builds all over again as you look forward to the next day.
