Had both. Love both. Just depends on what you want. Customization options on the S3. Top notch quality and cohesiveness on the iPhone. If I could, I'd switch every other day between the two.
Cane from the Galaxy s3 to the iPhone 5, loved my Galaxy s3 but it has weak radios and could not hold onto signal where the iPhone just works, I'm an android person but I need a device that does calls/data consistently
Best buy gave enough on trade in on the Galaxy s3 to pay for my iPhone
The s3 radio is weak and the battery life is the pits . I came over to the iPhone 5 and all I can say is it works like u expect it too. I think u would be happy with it
Not sure how people are saying they have use both, no question in my mind if you can get your hands on samsung galaxy "34" it will be blow the iphone 5 out of the water, lol.
