How everyone, I have a galaxy s3 hence my name. I have owned this phone for approximately 1 year. During my earliest stages of learning about the phone, I realized how much better than an iPhone it truly was. Anything and iPhone could do my galaxy s3 could do faster and better. Then the fun began, I rooted my phone approximately 6 months ago. This is what a smartphone should be. I have 100 control over my phone, not 99 but 100 percent. My friends have nicknamed my galaxy S3, the iPhone killer. By the way, any apps that cost money, I don't have to pay for because of the different app stores available to rooted Android users. At this rate, I may not even move up to the S5 when it comes out.
The S5 is a significant upgrade from the S3. If I had an S3 I wouldn't hesitate to upgrade.
