I acquired the S3 on friday!
I find the phone operates without any sticking, crashing or anything of that nature. It has handled all processes and applications perfectly.
The camera is extremely good, from taking portraites / landscapes through to macro shots.
The screen is amazing and is a viewing pleasure.
I have 10mb wireless internet at home and the phone connects consistently shows at at 5mb download and 1mb upoad with speed test.
The phone is surprisingly light given the dimensions, its typically the first comment I get when a friend takes a look.
I am using the phone quite heavily on the wireless at the moment while I gather the applications I want, the battery life exceeds my expectations.
Albeit not the most technical of reviews however a positive review nonetheless
Note: the above comments are whilst the phone is in use on auto brightness and battery saving mode.
With reference to cases; as the screen has a large surface area I opted for something that covers the screen and a screen protector. (I also dont have insurance).
