Well i gotta be honest i didn't expect all this, after rumors filled the internet i was thinking that rumors were over selling the S4 but i was wrong the S4 offered much more than what has been rumored!
As I'm too sleepy here's what impressed me and maybe later i will share some more details...
1- PAUSE the video if you looked away and then resume the video when you look back.
2-take picture or video with dual cameras (the front and back cameras working the same time) this can be used in video calling too and chat.
3-take up to 100 pictures within 3 seconds.
4- have a dramatic picture if you are recording a dancer the dramatic mode will take seceral pictures of the dancer and will put it into one picture making it like a dramatic scene.
5- add sound to your photos record a short sound clip and attach it to your picture.
6- wave your hand above the screen to scroll down or up!in gallery, internet browser and for answering phone calls too! This way if your hands are dirty/oily you don't have to touch your phone! The phone will respond to your hands even if you were weari g a gloves too.
7- turn the s4 into a sound system and play the same song with other S4's without having an internet connection or even a wireless network up to 8 phones and you can assign the left/right/center speakers!
8- S Translator supporting 9 languages with internet connection just whatever you want and the phone will translate it to the other language, even better without internet connection the phone has more than 3000 pre-saved sentences in different languages catagorized imto groups to help you get by if you were in a country where you can't speak their language!
9- too many accessories like bracelet to track your body calories...and many other checks.
This is what impressed me the most there should be more of course but I'm really too sleepy now...but to keep it short... This is my next phone inshallah :)
