DO NOT buy this phone I switched from the Iphone 5 to the GS4 3 weeks ago. I put the phone in a neoprene sleeve and went for a run. The moisture sensor was tripped and the phone was ruined. I've run half marathons with my iphone and never had a problem. I went to Samsung and they told me to pound sand. If you workout...this is not the phone for you. FYI...
