I went from an iPhone 4 to this phone for the camera specifically but I love all of it. The larger screen is clear the camera is awesome and I rarely have connection problems.
I had the Samsung Droid Charge and upgraded to Galaxy 4. What a big difference. Speed is good. I like the ease of functions, shortcuts and customization to the phone. Excellent pixels for camera. I just got an upgrade that included camera shortcut default on lock screen as well as album art for lock screen once in Iheart, Amazon, or Music. Screen is pretty big for one hand texting but it is a fair trade for YouTube and Netflix quality. Awesome machine!
