I used the Samsung g600 for 1 year now ( o2 ).
Lets Break The bull-shit here Ok.
The phone is Very Very simple to use, The interface is Awesome as the phone stores data e.g. you go into the menu and press setting and then press the Red button which resets to home wallpaper, when you press the menu button again it take you straight to setting so you dont have to scrool through again.
Battery life : I was very Surprised how good is the battery life,
2-4 days ( Using the phone games and listening to music, when not usig alot just making calls I quarantee you will have at least 5-8 days of battery life.
Camera is very good. When using Macro for closing capturing.
quite loud , good quality, For the true music fans i would recomend External Speakers for Better Quality.
Internet Browser very Easy to use and Fast ( Trust me you will be surprised ).
My rating is 9.5/10
