Here’s a great testimonial from a new Galaxy S4 owner who equipped his new mobile with a HANDeBand!
Something that works great with the new Samsung Galaxy S4 (and other mobile devices) is the HandeBand – http://handeband.com/. I attached one to the case of my S4 the day I received the phone. It makes it much easier to hold, props up the phone like a stand to watch movies, read e-Books and make it easy for the conductor to see my MBTA Mticket. I also had one for my Galaxy S and had to get one for the new phone.
