Well... got the Galaxy S3 since August 11... it's been 11 days. What can I say?.. ok
1. NO LAG... I haven't seen any lag what so ever. The phone is very smooth.
2. SPEED 4GLTE: I'm just going to say... WOW!.. yesterday I did a speed test and got 18MG of download and 4MB of upload. It's insane. You will love when uploading videos to Youtube.
3. Camera performance in low light: Excellent... check out this video of a concert I went last weekend - http://www.youtube.com/watch?v=bsFJxS_O-wo
4. WIDGETS: I'm really loving this...
5. SCREEN: the resolution is amazing. Videos and photos are so sharp and crisp. The screem is gorgeous.
6. BATTERY: it goes all day.. no problems here. Sometimes I think is better than the iPhone's battery.
7. SYNC: I can sync my phone with my calendar and contacts with my mac.. even better since it's all online. Just like icloud.
I don't think I'm coming back to iPhone
100% agree.
Since I used to have smartphones, I always had iPones (3G,3GS,4)until the day, the S2 came out.
Now owning a S3 since may, couldn´t be happier, really enjoying that beast.
Can´t imagine ever going back to an iPhone.
