I have been through a lot of Phones in my life. My first Smarty was the orignal Moto Droid. I am a Truck Driver so take this with a grain of salt.The S3 has a great screen as everyone knows. At 4.8" I treat it like a laptop not a phone.First thing I bought was a good case I do not put it in my back pocket, front pocket,shirt pocket I keep it in the case. I work in Construction not an office, I think it is pretty well built. The more times I charge the battery it seems the longer it last. I could get 2 days out of a full charge I do not think there is a faster smarty out there right now. I am not nervous about taking this phone on any construction site.I have had my Moto Droid for 3 years and it served well I think this will do the same
