samsung galaxy s3 is really fragile but htc sometimes in a long period of time the slide to unlock does not want to unlock at all or the sound breaks and you have to turn it off and then on my dad has a htc and it starts to break and this htc he has is only a year old and now he had to get a new one. so if i was you id pick iphone it better.
I like the S3. How big is too big? It's nice to watch videos on amd play games. It's easy to fit in your pocket despite what done people would say. You can use SBeam to share anything with another Galaxy phone from S3 and up. Unlike the iPhone or the One X it has expandable storage, unlike the iPhone that only has 5 GB of free cloud storage the S3 has 50 GB of Dropbox cloud storage. Also, the iPhone is the most fragile phone I know. I work at a Sprint store with a service and repair center in it and people being in their broken iPhones all the time to try to get them fixed. I've only seen one S3 that was broken.
