After using galaxy s4, I will upgrade still to galaxy s4. you can say I have been almost like brainwashed into loving this awesome phone. I came from a galaxy s3 and jumping to s4 I immediately noticed the difference. the screen is indisputably beautiful with full HD recording and playback capabilities. the battery life is above average under normal usage it gets me through the day without charging it and on 3g. my s4 is running kitkatt and I must say I sometimes push it to the limit to make it fail but it always come through. it handles games marvelously. the phone although made of plastic, it feels and looks very classy. this phone completely satisfy my needs and all I expect from a phone.
